I need to find the original value of X for a particular percentage of Y.

Example

If 65% of X = 100(being Y), what is X (for this example it's apx 155) but I need exact numbers.

Cheers.

first we need some vocabulary (vocabulary in math ?! yes, vocabulary in math).

"Percent" is a fancy word for "out of 100" or "divided by 100." so 65% means 65/100

in math, "of" means "multiply." so 65% of means "65/100 x"

so now, rewrite the equation:

we have:

Now solve for
