divide the number by 100, then times the answer you got by the percentage you wanted to find out. So if i wanted to find 64% of 32. I would:
32/100=0.32
0.32*64=20.48

EXAMPLE: what is 25% of 75?
first, change 25% into a decimal. which would be .25.
then, multiply .25 with 75. which would be 18.75.

Number of total marks x100
To find out what percentage of a number a certain number is, divide it by x/100. In this instance, 63 / (70/100) = 90.This is the opposite of what you would do if you were given the total, and told to find a certain percentage.
Lets say we have the number 500 and we want to find 50% of this number, this is easy to to in your head so i'm using an easy number so you see how the equation works. you simply divide the number you have by 100 (converting it into a percentage) then multiply it by the percentage you want to know 500/100=5 5*50=250, so 50% of 500 is 250. quantity/100*percentage value. If you have a percentage of a number and you want to know what number that percentage is of a quantity you do (sticking with the same numbers): 50%/100*500=250
Multiply that number by the decimal equivalent of the percentage. 70% of 340 = 340 x 0.7 = 238
If you take '2' and '4', then 2 is 50% of 4. To calculate that, use (2/4)*100 to get the percentage. So to find out what percentage number 'x' is of number 'y', use (x/y)*100.
a number increase from 500 to 625 find the percentage increase
I guess you mean find the percentage of one number of another, eg what percentage of 100 is 30: Divide the number for which the percentage of the other is required by the other number (making it a fraction of the second number) and multiply it by 100 %.
The answer depends on whether you wish to find one number as a percentage of another or if you want a given percentage of a number.
find it urself fool
You take your percentage and divide it by 100 then times it by your whole number or what you are trying to find the percent of
To find the percentage of one number you divide the numbers then multiply the answer by 100. For an example, if you want to find the percentage of four that the number three is you divide three by four and then multiply the result ,which is 0.75, by 100 and your result or percentage would be 75%!
Number of total marks x100
For save percentage, you divide the number of saves over the number of shots on goal.
The answer depends on what the percentage problem is. The equations will be different depending on whether you want to find:one number as a percentage of another,a given percentage of a number,the percentage change applied to a given number,find the original number if given the number after the percentage change.
Get the denominator to be 100.
A percentage is a portion of 100. so to find the calculation of a decreased percentage, you subtract.
To find the percentage of a number, multiply the number by the percentage expressed as a decimal or fraction. For example, to find 20% of 80, multiply 80 by 0.20 or 1/5. This will give you the answer of 16.
