How do I find what percent of a number another number is? ?

Question

What's the formula?

Thanks

Answer 1

If the numbers are for example 28 out of 35; you do:

28/35

=0.8 which is equal to 80%

I hope I've helped =)

Answer 2

a = what percent of b?

Example:

50 = what % of 100

50 = 100x

x = 50/100 = .5 = .5*100 = 50%

100 = what % of 50

100 = 50x

x = 2 = 2*100 = 200%

Answer 3

Formula is :

Another Number

-----------------------  X 100

Number

or

( Another number ÷ Number ) X 100

Answer 4

All a percent really is, is a fraction of 100 ("percent" = "per hundredth").  So usually it's just a matter of dividing, then turning the decimal or fraction into a percentage.  300 would be 50% of 600, because 300/600 = 0.5 = 50%

When I see a problem like "What percent of 30 is 12?" or "80 is what percent of 5000?", I just try to translate the words from left to right into an equation, then solve the equation.  This helps ensure that I don't make any errors by dividing the wrong way.  "What percent" becomes the variable, "is" becomes equals, and "of" means to multiply.  So "What percent of 30 is 12?" would be:

x* 30  = 12

This means x = 12/30 = 0.4, so the answer is 40%
