Eg...45 % of 80
Eg....45×80 =3600 and divided it to 100 answer is 36 use this simple
Method...
I LOVE U BRO THX
Thx for helping!
45% is four 10 percents + one 5 percent = 4*8 + 1*4 = 36.. simpler than the traditional method..
Sema bro
Omg what the frick it workssssssss
At the beginning when he said "hopefully you know what 15% of 80 is" I was literally sweating 😭😂
Instead of eighty he said I and a t I laughed so hard
I was about to choke
Thought it was just me 😂
i dont get that at all..
@Gad Family why do you have to act such an idiot? You have a bad temper bro. 😉
@TTVMarliwhirl why cant you work out percentages? they are simple problems. you have the mind of a five year old child? 😉
I feel like everyone in the comments is a primary school kid, and here I am trying to remember how to do this in uni
A lot of adults struggle with math. No problem. What are you studying at uni?
@@tecmath Dentistry in New Zealand! haven't needed maths for a few years now as its mainly science-based!, this video made it super easy to understand again though, thank you!!
@@emmasimons4030 well thanks! Good to see you guys in New Zealand are doing well.
@@tecmath where can I get the video showing 13%, or 58%?
Nope I’m still in high school 😒
I love how I see youtubers shows simple tricks to solve a problem, and then in the comment section people showing a much easier trick 😂

Why can't all math teachers simplify things like this. It seems like the teachers at my school took pleasure in confusing everybody.
wow. you sure are a looser. have fun on the other side of the world.
imagine calling someone a loser.

He wasn’t helpful. I still don’t get it
Bro I never learned this method in school and now I feel so freaking smart. I’m not but like damn.
Wtf?!?!
Nice
There’s an easier way for eg.
30% x 40
30x40=1200
1200 / 100
=12
Use this method it helped me so much for the past years. 💞
@@6xmaaaa appreciate it
Studying for the ASVAB, don't know what I'd do without your videos. Seriously, bless you for putting up quality education content for those of us who do not have access to personal tutors or instructors.
I typed in "math" in the search box because I couldn't fall asleep. This didn't disappoint because I slept like a baby last night!
You should have typed how to fall asleep
U dont make sense
I get you you searched in math because it's boring haha.
Lol
Buwahaaaaaaaaaaa
15% of 80
10%=8
5%=4
Add them=12
so true
The easy way is that you do 15% divided by 100 give you 0.15 times 80 = 12. I hope it makes sense
@@Mariana-gd9nx you need a calculator then...
thats true!!

Thanks so much my guy! My teacher takes more than 45 minutes explaining super easy math like it’s REALLY HARD math, but you simplifying it makes it so much better 🤩
When you learn it at 5th grade and then forget everything 😔

I literally forgot everything that i learned in 6th grade now i don't know anything :"(
Samee😭😂

@@k7hle_376 Lol it wasn't pointed directly at you 😭
I have a cool technique for percentages of large numbers. I divide numbers into their tens, hundreds, thousands etc. constituents, apply the percentage to each one, them sum the results. So to do 20% of 1485 (composed of 1000, 400, 80 and 5), I do:
(20% of 1000) + (20% of 400) + (20% of 80) + (20% of 5)
= 200 + 80 + 16 + 1
= 297
Thanks mate that really helped a lot with my homework
+bennemann 20% is the same as 1/5 so just divide 1485 by 5 ( =297) ... or divide by 10 and double your answer. e.g. 1485 /5 = 297 or 1485/10 = 148.5 the x 2 = 297
+Andrew Murray hahah....u stole the show !! :D
Bravo
still dont get it
29 year old here about to go back to college having a meltdown over maths.. thank you for this!!!
As a former non-traditional student, good luck in your studies. If you’ve never done so, check out the Kahn Academy. MANY topics taught as expertly as this instructor does.
Give yourself time to learn and permission to fail. First step in learning is not being afraid to admit you don’t know.
Louder for the people in the back 😂
🤣🤣🤣🤣
plug in your headphones/speakers.
Cheese pie
Right🤦🏽♀️
yeah
Just multiply by moving two decimals is way easier and faster.
15% of 80 = 0.15 x 80
or (15 x 80) / 100 to make it even easier.
I've struggled with percentages and always have when I get worried about a test or anything I always come to this Channel and it always helps so much!!!
My teacher forced me to watch this during the whole COVID-19 thing for online classes.
Extility Xmorph me to I don’t
i dont think schools are even open during this pandemic. nice try disabled one!😂
@Anant Tiwari oh. I think Ingot caught up with the news on social media. Yeah, schools are open. My bad. Thanks 4 the heads up.
I'm studying for my asvab, I been 7 years out of the school system so I'm pretty rusty but after watching this video I completely understand percentages and its all because he took the time to REALLY explain. to all struggling with math this channel is the absolute best! best of luck to everyone.im slaying that test.
Damn I was always bad at maths and I still couldn't do those tests, its like my brain blocks with numbers 😟
Your not alone
Ha! Tomorrow I’ll be taking the ACT and I can’t even find the percent of a number ;), just make you feel better
Melani Miller You poor soul
what do you have against math? it is a good subject. nothing wrong with it. take care buddy and take them meds! 😁
I find calculus easier than doing percentages in your head. No lie
I was getting tired of looking stupid trying to work out the percentage of my restaurant bill to give a tip. I always pulled out my trusty calculator. This is awesome. If I knew about this at school I would have excelled at Maths.
*when your maths teacher doesn’t teach you and just throws the work at you* he doesn’t even teach us how to do stuff-
Hahah same😌😂😭
Hey.. You been looking at my lesson plans?
@@tecmath ooooooooh :o
exactly they just take tests not tech
I kinda actually like it when the teacher just gives us the work instead of teaching us
I really thank you my daughter came in with homework and goes mommy I don’t understand it. When I looked at it I said hold on.... me goes to TH-cam lol it’s been so many years since I was in school and math wasn’t my strongest subject, but this really breaks it down I can’t forget after this.
Easiest way to find a percentage is to take the number for example 42 divide by 100 and then multiply by the percentage you're trying to find for 50%
i just multiply it without changing th epercentage and then remove the percentage 80 x 15% = 1200%=12.0
WIN
Perfect
Thanks Man U helped me out
wow. thanks man. this is way easier
Crap! This is WAY freakin' easier and faster to solve the problems! THANKS!!!
Basicly in easier ways lets say 55% of 360
so what you would do is divide 360÷100=3.6
so you take 3.6 and multiply it by 55% and you get 198 as seen in video hope this helped :)
this video was really helpful, keep up the good work man!
I have struggled with percentages my whole life and this video has helped me SO much! Great way of explaining!
bruh wth!!! why didn't they teach me like this in school!!
Donald Shipp II because the school system is the opposite of learning

if you have to ask that question, you better catch up and FAST!
what grade do you do this in me 6th grade

Who is watching this in 2019?
I came back in 2020 as we were revising percentages again
Meeeeeeee
Ali Adel meeeeee
Me
Why?
Me
or you can turn the percentage into a decimal and multiply
55% of 360
.55 x 360 = 198
this helped so much hhahaha thank you
You just multiply decimals without a calculator? Are you a god?
if you turned to decimals, then you need to use the calculator machine which we try to avoid.
This video explains how to calculate mentally. If you can calculate .55 x 360 in your head then why are you watching this video
Oh my God... thanks so much for the perfect explanation. You're the best. You have no idea just how much you've helped me right now. I was stressing out because I just didn't get the way someone else was trying to teach me.
I have an entrance exam booked in 3 weeks from now. You've really made my day. Love your work, mate. Cheers.
Thank you I passed my state test because of this
😁☺️😋✌️️💖
Mercy Watermelon What grade are you in?
Mercy Watermelon
My life as Mercy WOW CONGRATS!!
My life as Mercy aa
My life as Mercy What you get did you beat my streak of double 4’s until 8th grade
not me needing this for my maths test today
You have actually explained this in a way that I actually understand. First time in my life. Thank you.
For 25% just half it and half it again. Much easier!
Paul Wares I know right, that's what I got taught in school because 50 is half so divide by 2 or just mentally half it then 25 is half of 50 which is half of 100 so divide by 4 or half it and half again
Divide by 4
Paul Wares same
Paul Wares thank u!!
Paul Wares wdym by half? 2? 50?
This is an excellent video, well designed, instructions are easy to follow, and it's fun.
Good idea to add the exercises, makes it easy to practice. You're a brilliant teacher :)

You taught this SO WELL! Thank you!
Thank you sir. You are the best math teacher ever. xD
Wow. I love you all. Thank you 4 the support everyone.
Thank you. This method really helped me work it out. I’m rlly good at algebra and other areas of math but percentage is something that makes me struggle a bit so thank you. I’ll also subscribe and watch other videos
Thanks so much for your simple, informative videos! You’ve helped me brush up on my maths skills for an exam I have coming up!
I’ve watched your videos on and off for several years, love the way you teach maths.❤
Thank you so much for giving us examples and making us work out some for ourselves.
This technique is from Vedic Mathmatics which is taken from Atharvaveda. It was invented way back before 3000 years in INDIA. PROUD TO BE AN INDIAN
you still live in a shithole
Just do 15 x 8 = 120 then erase the first zero since it is a double digit %.
so it is 12
DrE38 15x8 just 1x8=8 then 5x8=40, remove zero so it will be like 8+4=12 then add 0 lol

Thank you so much!! You helped me a lot! Now I’m feeling proud of myself for answering them all correct:)
i wish he was my teacher, all the math teachers are so vague when they explain ;__;
Great dude If I had had these lessons when I was 8 years old,I would have loved maths before.I am preparing numerical test and this is helping me out Cheers
Helped me out a lot ! Thanks , my man!
Thank you! This is SO helpful!
Good info and a great method. Thanks for sharing!
Freekin awesome! My life would have been so much easier had I learned this years ago as quick as I did just now
I'm not joking when I say this just changed my life. I moved from England ( the land of not tipping servers, mainly) to Canada ( tip everyone ) and I've always struggled to figure out the 15 percent tip. I usually didn't bother and guessed because my teachers said I was stupid, and that stuck with me. The simplicity of it blows my mind! I'm staying up all night to study math now...and a big middle finger to all you math teachers who could not explain math in a way that I could understand. Thanks tecmath. :)
Thanks in in primary school in year 5 and I'm off rn so this really helped me learn how to do it!

Thank you so much, this makes so much sense
Thanks I have a math test tommarow and totally forgot how to do this
I just find 1% of the quantity and then multiply by the percentage they ask for. For example if they ask for 8% of 25 I find 1% which is .25 then times by 8 which becomes 2.
Like it
MrNintoku
it works but becomes kind of hard for say 55% of 360.
3.6 times 55
45% of 860.
8.6 times 45
I watched this once and completely understood thank you for the amazing video
Thank you so much this helped me a lot with maths its so simple i dont know why they make it so many steps :D

I have read several (young ladies) critical comments of this Mans voice. He sounds to me like an Australian , and actually has a very soothing voice like my Dentist. He would make a wonderful story teller. I do wonder if people from other countries realise that we Australians find their accent hard to understand at times.Interesting these people have all been helped for free in these videos. I am so grateful as a Homeschool Mother for these very valuable lessons.
Where have you been all my life! AWESOME VIDS THANK YOU!!!!
Thank you so much! Percentage questions have been destroying my math score since i discovered what math was. I love and appreciate this method!
Thanks! really helped for my upcoming maths test!
Again thanks for the help n the other video!!!
When doing 25% I find it easier to divide the number twice instead of your method at 8:50 e.a. 860/2=430 430/2=215 ; Otherwise great tips, I appreciate the help.
Exactly what I do too, much simpler & quicker
this helped so much God bless you
you made that so easy to understand sooo thank you!
This helped a lot thanks!
Price X percentage
( % your looking for) ÷ 100
Example
1200 X 55 ÷ 100=660
So 660 Is the 55% of 1200
easy formula
26 is what percent of 268
@@joycesiyangaphi3327 268 x 26=6968 divided by 100=69.68%
Great explanation,it helped me a lot.
I LOVE YOUUUU!
I don't get it
When the percentage is a two digit number its always gonna start with a decimal
45% of 80
.45×80=36
---------------------
When the percentage is only one digit start with your decimal but add a zero followed by your percentage
4% of 80
.04×80=3.2
This method gets rid of the subtracting Hopefully this helps and is understandable.
thx
da real mvp
tnx, made it a bit more easier
Dude, i got everything right on the questions on the video thanks to you!
very well done
I am half in the bag right now and I can still do this mentally because of this guys calm voice.
My Korean mother in law is excellent with math despite only having gone to school up to 5th grade. She came to America when she was a teenager, and owned her own beauty salon by 21 years of age. She knows math because she knows money! She taught me this trick one day when I was trying to calculate how much to tip at a restaurant.

Can't believe anybody finds this a revelation. Why would you not already use these methods naturally?
Exactly my point! My math skills are the only thing that has held me back from my goals in life. Math, I think anyway, is the most important in life skills, math is everywhere and everything. I learn it okay, but I lose it just as fast! I remember checking out a book from my school library titled "How to Overcome Math Anxiety", when I was in the 9th grade.Needless to say, didn't help. I've had to rely on my stronger attributes to, just like you say, "stumble through life." Someone told me that I read too much into the equations, maybe that's it, maybe I just can't see the forest for the trees.
The fact that people /do/ find this to be a revelation means that he's helping people out. Different people need different help, so insulting people that do come to youtube in their extra time in order to learn is not only rude, but discouraging and harmful.
Gary Kovach
O my gosh, I think you read* it in my mind xd
Yes sir, you make sense. It doesn't matter the IQ, what matters is how one sees the problem. Having the right teacher to explain how something works is a key factor, some of us just can't see the forest for the trees. Good post.
thank you for helping me with my homework and possibly my whole unit!
