This is so helpful. I was really worried today because tomorrow I have school, and we are doing percentages. I looked at every single video until I found this. My life has completely changed from this one video..I can't thank you enough God bless you. Thanks again!!
I have not practiced or touched it for long but today in a test i have had this problem, it took me too long to make the right answer and as i saw the title of this video it made me deeply interested the way it is taught is such a time saving trick. I like it, it is very good!!!!!!!
Also remember that 4% of 75 is the same as 75% of 4. The math behind this is easy... (4/100 * 75 = 4 * 75/100) through the commutative property of multiplication. So, you can "pick" the easiest way to do think about it.
That’s what I was thinking as well. I accidentally worked out the % of opposite number, and the answer was same, I tried out with other numbers, % of both the numbers it was the same. So it’s better to work on which ever is easy to calculate. Thanks for the confirmation.,, now I am confident it works for real. hehe.. 👌😜😬
The key to this percentage calculation is to be good with percentage parts and fractions. 10% is 1/10th 5% is half of 1/10th i.e. 1/20th 20% is 2 * (1/10th) or 1/5th And lots and lots of practice + your multiplication / addition skills will come to play.
Still there another easiest method than this Example.:: 1.20% of 40 Just take a point from the end i. e. 4.0-->which is 10% of 40 Similarly 20 %of 40 =10% of 40+10%of 40=4+4=8... Example 2: 61% of 30 As said in the above example 1 Same... Take a point before the given last number.. i. e. 3.0 which is 10% of 30.. Now 60% of 30= 6×3.0=18 And to calculate 1% of 30.. We have to take a decimal point before the last two numbers.. ie..1% of 30=0.30 So 61% of 30=18+0.3=18.3 Example 3: 43 %of 25 10% of 25=2.5 1% of 25= 0.25 So here 40% of 25=4×2.5=10 3%of 25=3×0.25=0.75 43% of 25=10.75 Hope useful for someone...
One of my favorites is the divisible by three trick, add up all the digits (and if it's still bit too large do it until it's not) and if that's divisible by three the number you started with is. Same with divisible by six but only for even numbers :)
What? Are you trying to explain how to determine whether a number is divisible by 3, and divisible by 6? Edit: I guess we are saying the same thing, I just didn't quite understand what you were saying when I first read your comment, hence my diatribe and lengthy response. I just want to be sure people get the right information. For 3, you cast out 3s, it's easier than summing all the digits and seeing whether it's divisible by 3. Example: 13569 You "cast out" that is scratch out/throw away, all numbers, or sums of numbers, that can be divided by 3. For 13569 you can just scratch out 3, we know it's divisible by 3, also, 6 and 9, they are divisible, then finally, 1 and 5, because together their sum, 6, is divisible by 3. this is easier than going 1+3+5+6+9 = 24 which then needs to be checked if it is divisible by 3. And while this number/example isn't too difficult, for a number like 123,456,789 adding up all the numbers may not be quite as easy, assuming you haven't memorized the sum of course. By casting out threes from 123,456,789, we can scratch out the 1 and 2 as they total 3, a multiple of 3(meaning it is divisible by 3), then the 3 of course, also 4 and 5 as they make 9 which is divisible by 3, followed by 6(clearly divisible by 3) then 7 and 8 (which make 15 and is divisible by/a multiple of 3), and finally 9, another multiple of 3. That means you scratched out all the numbers and therefore the whole number itself is divisible by 3. This is easier than adding up all the digits and dividing by 3, well, unless you memorized the fact that the sum of the numbers from 1 thru 9 is 45(which is divisible by three). If I scrambled up all the numbers like, 274,813,596, that's just 123,456,789 written with the numbers in a different order, it may not be so easy. The divisibility rule for 6 is easy, the number simply has to be divisible by both 2 and 3 to be divisible by 6. So yes, it has to be an even number(the definition of being divisible by 2) and also divisible by 3. So if you want to know if a number is divisible by 6, just check first if it is an even number, then make sure it is divisible by 3, if yes, the number is divisible by 6. And finally, by the way, if you are interested, since 123,456,789 is divisible by 3, we know that 274,813,596 is divisible by 3 given the rule. And if we want to know if 274,813,596 is divisible by 6, we check first if it is even, which it is, it ends with the number 6, thus making it an even number, then we see if it is divisible by 3, which it is as shown above, so as it is divisible by both 2 and 3, the number 274,813,596 itself is divisible by 6. 274,813,596 divided by 6 is equal to 45,802,266. P.S. If you are interested. To test whether a number is divisible by 4, just check the last two digits of the number, if it is divisible by 4, then the entirre number is divisible by 4. example: 50,124 Just check the last two digits, in this case 24, is it divisible by 4? Yes (24/4 = 6) So the number 50,124 itself is divisible by 4. To test whether a number is divisible by 8, just do the same thing, but with the last three digits(instead of the last two). example: 50,124 Check the last three digits, 124. Is 124 divisible by 8? No, 124/8 = 15 with a remainder of 4. So the number 50,124 is NOT divisible by 8 (even though it is divisible by both 2 and 4) And it also happens to be divisible by 2 and 3, so also 6, which makes it an interesting number which I picked at random. The divisibility rule for 7 is a bit complicated so I won't explain it here. And I'm sure you know the divisibility rule for 9 is the same as 3, just cast of 9s. And mind you, just because a number is divisible by 3 does NOT mean it is divisible by 9. Case in point, 15, divisible by 3, but NOT by 9, obviously. However, all numbers divisible by 9 ARE also divisible by 3 (as 9 is just a multiple of 3). I assume you already know the divisibility rules for 2, 5, and 10, they are really easy.
For example I say that 39% of 28 is 10.92 so just multiply the numbers by ignoring the percent and using "of" as "x" so 39 x 28 = 1,092 and divide 100 so 1,092 / 100 = 10.92 so boom you will always get the right answer if u use this method and works for ANY number but use it propely I USE THIS METHOD FOR MANY COMMON PERCENTAGE PROBLEMS
Use the immediately obvious facts that 10% of 45 = 4.5 and 1% of 45 = 0.45 to solve the problem. a) 30% of 45 = 3 x 4.5 = 13.5 b) leaves remainder of 4% to solve for: 4 x 0.45 = 1.80 c) add results of step a with step b = 13.5 + 1.8 = 15.3 This method is generally applicable and quick to solve for any integer percentages of another integer - and explaining out the algorithm takes far more time than the actual mental manipulations of finding the solution.
this is actually the way ive always been doing it even before i started looking at shortcuts on youtube... it makes so much more sense than just mechanically calculating, which 99% of people won't be doing on a daily basis and it's better to be approximately right and perfectly wrong.
22% of 30 is very very amazing step this step clear my all concept or wesy bhi is way sy kisi bhi digits ki % nikali gay Wo bhtt easy tariqy se nikl aa rahi he thanku so much 😊
Hey❤️,God loves you and wants you to experience peace and life- abundant and eternal.But we choose to disobey God and go our own willful and sinful way. This results in separation from God.But Jesus Christ died on the cross and rose from the grave. He paid the penalty for our sin and bridged the gap between God and people.You must trust Jesus Christ as Lord and Savior and receive Him by personal invitation to receive that free gift and eternal life, think about this, have a blessed day💕
Can you solve this equation without using a calculator. 50+50-25x0+2+2 = ? Watch this video for the correct answer th-cam.com/video/3MZNRXgR7H8/w-d-xo.html
34% × 45 45.0+5.0 = 50 | 5 = 50 × 0.1 34 × 50% = 17.0 17-1.7 = 15.3 This is how I do it in my head. I just keep moving things around and turn it into multiple simpler equations. With enough practice, you'll solve this almost instantly. Once you realized the patter of numbers, you'll just guess/estimate and it will most likely be correct. Hahaha. Somehow, it's like magic.

Wow amazing I liked this method of calculating percentage sir.
Thank you. I needed a quick refresher. In about 10 secs it was all back. Thank you so much!
The key to this percentage calculation is to be good with percentage parts and fractions.
10% is 1/10th
5% is half of 1/10th i.e. 1/20th
20% is 2 * (1/10th) or 1/5th
And lots and lots of practice + your multiplication / addition skills will come to play.
Nice
Easier way:
Example one: 40 degrees * 20 = 4*2= 8.
Example 2: 22 of 30= 2.2*3= 6.6.
Example 3: 61 of 30= 6.1*3= 18.3.
Superb
I'm thinking that maybe this only works when one of the numbers has a 0 as a second digit, doesn't it?
@@agustindiaz3348 it works all for numbers
Hi bro
If you are already good at math this is awesome. It works for me. Thanks
This is extremely brilliant 💯
amazing.. way to learn and remember ..complex thing easyly
Short and comprehensive video. Thank you sir
I usually find 20% of anything by simply dividing it by 5۔ )knowing that 20% is 1/5th) e۔g۔ 20% of 30 will be 30/5=6۔
Your method is very handy too۔
I like the way how you use your common sense. Thanks! It would be a great help👍
I really love the tricks.its very helpful
Thank you sir! This will help with the kent test
Amazingly awesome!
wow. my life is forever changed. this rocks! 👍
Now what?
Still there another easiest method than this
Example.::
1.20% of 40
Just take a point from the end
i. e. 4.0-->which is 10% of 40
Similarly 20 %of 40 =10% of 40+10%of 40=4+4=8...
Example 2: 61% of 30
As said in the above example 1
Same... Take a point before the given last number.. i. e. 3.0 which is 10% of 30..
Now 60% of 30= 6×3.0=18
And to calculate 1% of 30..
We have to take a decimal point before the last two numbers..
ie..1% of 30=0.30
So 61% of 30=18+0.3=18.3
Example 3: 43 %of 25
10% of 25=2.5
1% of 25= 0.25
So here
40% of 25=4×2.5=10
3%of 25=3×0.25=0.75
43% of 25=10.75
Hope useful for someone...
Thanks for the tricks, its truly helpful

For 3, you cast out 3s, it's easier than summing all the digits and seeing whether it's divisible by 3.
Example: 13569
You "cast out" that is scratch out/throw away, all numbers, or sums of numbers, that can be divided by 3.
For 13569
you can just scratch out 3, we know it's divisible by 3, also, 6 and 9, they are divisible, then finally, 1 and 5, because together their sum, 6, is divisible by 3.
this is easier than going 1+3+5+6+9 = 24 which then needs to be checked if it is divisible by 3.
And while this number/example isn't too difficult, for a number like 123,456,789 adding up all the numbers may not be quite as easy, assuming you haven't memorized the sum of course.
By casting out threes from 123,456,789, we can scratch out the 1 and 2 as they total 3, a multiple of 3(meaning it is divisible by 3), then the 3 of course, also 4 and 5 as they make 9 which is divisible by 3, followed by 6(clearly divisible by 3) then 7 and 8 (which make 15 and is divisible by/a multiple of 3), and finally 9, another multiple of 3. That means you scratched out all the numbers and therefore the whole number itself is divisible by 3.
This is easier than adding up all the digits and dividing by 3, well, unless you memorized the fact that the sum of the numbers from 1 thru 9 is 45(which is divisible by three).
If I scrambled up all the numbers like, 274,813,596, that's just 123,456,789 written with the numbers in a different order, it may not be so easy.
The divisibility rule for 6 is easy, the number simply has to be divisible by both 2 and 3 to be divisible by 6.
So yes, it has to be an even number(the definition of being divisible by 2) and also divisible by 3.
So if you want to know if a number is divisible by 6, just check first if it is an even number, then make sure it is divisible by 3, if yes, the number is divisible by 6.
And finally, by the way, if you are interested, since 123,456,789 is divisible by 3, we know that 274,813,596 is divisible by 3 given the rule.
And if we want to know if 274,813,596 is divisible by 6, we check first if it is even, which it is, it ends with the number 6, thus making it an even number, then we see if it is divisible by 3, which it is as shown above, so as it is divisible by both 2 and 3, the number 274,813,596 itself is divisible by 6. 274,813,596 divided by 6 is equal to 45,802,266.
P.S. If you are interested.
To test whether a number is divisible by 4, just check the last two digits of the number, if it is divisible by 4, then the entirre number is divisible by 4. example: 50,124 Just check the last two digits, in this case 24, is it divisible by 4? Yes (24/4 = 6)
So the number 50,124 itself is divisible by 4.
To test whether a number is divisible by 8, just do the same thing, but with the last three digits(instead of the last two).
example: 50,124 Check the last three digits, 124. Is 124 divisible by 8? No, 124/8 = 15 with a remainder of 4. So the number 50,124 is NOT divisible by 8 (even though it is divisible by both 2 and 4) And it also happens to be divisible by 2 and 3, so also 6, which makes it an interesting number which I picked at random.
The divisibility rule for 7 is a bit complicated so I won't explain it here.
And I'm sure you know the divisibility rule for 9 is the same as 3, just cast of 9s. And mind you, just because a number is divisible by 3 does NOT mean it is divisible by 9. Case in point, 15, divisible by 3, but NOT by 9, obviously. However, all numbers divisible by 9 ARE also divisible by 3 (as 9 is just a multiple of 3).
I assume you already know the divisibility rules for 2, 5, and 10, they are really easy.
