oh my gosh. I am so proud of myself. I struggled with percentage. so I watched your video 2 times, omg, I got it. I got it!!! you have no idea how much I appreciate you for making this video. now I'm gonna practice even more. for years and years didn't make sense to me but now it does. thank you a lot. God bless
This method is actually really intuitive. For the longest time, computers only had hardware for addition and subtraction. Before the invention of multiplexers, computers would multiply/divide by just repeating simple additions & subtractions (ex: 6x3 = 6+6+6). Your video pretty much follows that same rule: instead of learning something challenging, stick to what you’re good at doing to solve complicated tasks.
@@huss2600 You just move the decimal point to the left twice and then times your answer by the percentages. E.g. 25% of 600. You would do 600 divided by 100 which is 6.00. Which then u do 6.00x25
Depending on how well you remembered your multiplication tables, it may be easier to divide by 4 for 25%, in my opinion. They had me learn multiplications 1×1 through 12×12, though my memory got a little rusty for some of the bigger numbers/products. Nonetheless, in my case I might be more efficient dividing my 4. I also think it might be easier to subtract 25% to get to 75% regardless of your memory. It takes one less operation and you have to calculate 25% either way
i do one times the other and move the decimal where it looks best. so 85% of 24 I do basically 85 x 24 = 2040 and move the point so it becomes 20.4 (I'll insert the decimal point as I'm reading it out). But the theory is basically just times them together and depending who you are and what memory you have I would suggest multiplying by any means that comes natural. I like putting figures with 0.5 into the other because a half is so easy to calculate and put aside until the end. when i see 85 i think 8times + 0.5times(just a half) so 85 x 24 I really do ((8 x 2 =16(then add a zero because the 2 is tens =160)) + (8 x 4=32)) = (160 + 32)= 192 then add half of 24, so 192 + 12 = 204 it seems longwinded but they are low numbers and it can be done in seconds. But there are many ways to times numbers together and I suggest whichever way you want to get there
Thats literally how i tought myself to to them because i always thought doing it through equations of for example 25% of 1250, 25/100x250 is boring and time consuming, but practicing these mind calculations can lead to very quick an reliable Outcomes
If you dont have the numbers on this list: follow these instructions. (divide further for decimals) Divide your number by 100 (now its 1% and can be used as a base for more multiplying.) Multiply that base by 10 times and use it for more larger number leaps. (76=70+6) If you fancy it, you can use even larger numbers. (76=50+20+6) Collect the numbers until you have the needed percentage necessary If you guys know a better method please tell me.
Nice! I also use that method, I learned how do percentages because of Minecraft (its a video game) 😂. I used the percentage on how armor protection works and it made me better in percentage.
10% = 7.80, 1% = 0.78. So just do 3x 10% and then add the 1% to it. To do that I would calculate 7x3 for 21 and then 0.80x3 for 2.40 to get 23.40 and then add the 0.78 to it for 24.18 Did this in my head and typed it as I did it so hopefully I didn't make some mistake as I was all adding it up. But you get the point.
I saw a comment where it says: ×% of = y% of x For proves: 26% of 70 = 70% of 26. To calculate 70% of 26 I usually go like this. 50% + 10% +10% = 70%. So : 50% of 26 is 13. 13+ (10%×2) = 13+ 20% 10% of 26 is 2.6. 20% of 26 is 2.6 ×2 = 5. 2 13+5.2 = 18.2 or 70% of 26 as well as 26% of 70. To go back to your question: 31% of 78 = 78% of 31. 78% = 100% - 20% (10 + 10) - 2%. 31's 100% is 31. 31 - 20 % (of 31) is 31- 10% - 10% . 10% of 31 is 3.1. 3.1 ×2 = 6.2 = 20% 31 (100%) - 6.2 (20%) = 24.8 (80%) Now: 24.8 - 2% (1%+1%). 1% of 31 is 0.31. 2% = 0.31 ×2 = 0.62 24.8(80%) - 0.62 (2%) =24.18(78%) That's what I would do at least but you really have lots of options
@ 3:47 for 75% . You said you take half 50% which is 12 and then you take 25% from 12 and got 6? Isn’t it suppose to be 3? I dont have knowledge so correct me if I’m wrong
Here I answer how to find 23% of 24. 23%= 25% -2% Let's start with 25% of 24. (50% : 2=25%) so 50% of 24 is 12, divide that by 2 and you have 6 which is 25% of 24. The second part is 25%-2% (1%+1%). 1%of 24 is 0.24. 0.24 ×2 = 0.48 (2%) 6(25% of 24) - 0.48 ( 2% of 24). 6 - 0.48 = 5.62 which is 23% of 24. That's what I would do at least but you really have lots of options.
I think your method is rather complicated. I normally just calculate 10%, then multiply it to get to percentage with factor of 10. Then add 5% for percentage with factor of 5.

To go back to your question: 3.36% of 90 = 90% of 3.36 So 3.36(100%) - 0.336(10%). 3.36 - 0.336 = 3.024 which is the 90% of 3.36 and the 3.36% of 90. Another example: 3.36% of 400. 3.36% of 400= 400% of 3.36 3.36(100%). 400% = 100% ×4 400%= 3.36 ×4 = 13.44 400% of 3.36 is 13.44 as well as 3.36% of 400. That's what I would do at least but you really have lots of options. I did it without a calculator.

One more trick:
Did you know?
x% of y=y% of x
Proof:
y/100*x=x/100*y
xy/100=xy/100
Example:
2% of 50=50% of 2
Try it!

It's easier in most cases to just multiply the percentage by the amount then divide by a hundred.
I think this will certainly be helpful for those looking to return to math. Very clear instructions.
If you want 1 percent just move the decimal point 2 times to the left

@@MalphasMikaelson im kinda retarded to understand that
Easy peasy man just 78×31÷100=ans
I saw a comment where it says:
×% of = y% of x
For proves:
26% of 70 = 70% of 26.
To calculate 70% of 26 I usually go like this.
50% + 10% +10% = 70%.
So : 50% of 26 is 13.
13+ (10%×2) = 13+ 20%
10% of 26 is 2.6.
20% of 26 is 2.6 ×2 = 5. 2
13+5.2 = 18.2
or 70% of 26 as well as 26% of 70.
To go back to your question:
31% of 78 = 78% of 31.
78% = 100% - 20% (10 + 10) - 2%.
31's 100% is 31.
31 - 20 % (of 31) is 31- 10% - 10% .
10% of 31 is 3.1.
3.1 ×2 = 6.2 = 20%
31 (100%) - 6.2 (20%) = 24.8 (80%)
Now:
24.8 - 2% (1%+1%).
1% of 31 is 0.31.
2% = 0.31 ×2 = 0.62
24.8(80%) - 0.62 (2%) =24.18(78%)

I appreciate you a lot!!
very good video
Good system that is practical in real life.

You could have written these in fractions like .20 equals 1/5 etc.
Just make it simple for them. "of" = "times", so 15% of 24 = .15 x 24 = 3.6

For 85 % couldn't we have just added 10% to 75 % and that would be easier ?
Thank you
This is fine if everything is 10s and 5s. What about when it gets harder, like 16, 18, 23, 44, etc.
Here I answer how to find 23% of 24.
23%= 25% -2%
Let's start with 25% of 24.
(50% : 2=25%) so
50% of 24 is 12, divide that by 2 and you have 6 which is 25% of 24.
The second part is 25%-2% (1%+1%).
1%of 24 is 0.24.
0.24 ×2 = 0.48 (2%)
6(25% of 24) - 0.48 ( 2% of 24).
6 - 0.48 = 5.62 which is 23% of 24.
That's what I would do at least but you really have lots of options.
Omg, I finally know how my dad does it so fast! 😂

Calculator, ain't no body asking for those percentages in RL.
I think your method is rather complicated.

Then add 5% for percentage with factor of 5.

gosh it is realy easy finally i got maths
Why don't you just divide whatever your number is by 4 if you want 25%?
What if i want to Calculate 37 % 83% or 48% OR 64% .. like it if that is the viewers question ❓ to ask
What if you wanted to calculate a percent that doesnt end in 0 or 5?
Get 5% and divide by 5 to get 1 % :p maybe
but how can we count 20%? please someone answer
find 10% and multiply it by2.. If you haven't figured out how... try this..
how about the odd one
Awesome :D
Ha!Because of Indian education I know it all.
How do you calculate 3.36% with this method?
at that point just use a calculator
I saw a comment where it says:
×% of = y% of x
For proves:
26% of 70 = 70% of 26.
To calculate 70% of 26 I usually go like this.
50% + 10% +10% = 70%.
So : 50% of 26 is 13.
13+ (10%×2) = 13+ 20%
10% of 26 is 2.6.
20% of 26 is 2.6 ×2 = 5. 2
13+5.2 = 18.2
or 70% of 26 as well as 26% of 70.
To go back to your question:
3.36% of 90 = 90% of 3.36
So 3.36(100%) - 0.336(10%).
3.36 - 0.336 = 3.024 which is the 90% of 3.36 and the 3.36% of 90.
Another example:
3.36% of 400.
3.36% of 400= 400% of 3.36
3.36(100%).
400% = 100% ×4
400%= 3.36 ×4 = 13.44
400% of 3.36 is 13.44 as well as 3.36% of 400.
That's what I would do at least but you really have lots of options.
I did it without a calculator.

0.24 ×2 = 0.48 (2%)
6(25% of 24) - 0.48 ( 2% of 24).
6 - 0.48 = 5.62 which is 23% of 24.

0.24 ×2 = 0.48 (2%)
6(25% of 24) - 0.48 ( 2% of 24).
