Multiply the whole by the percentage number and divide by 100.

For example, to find 30% of 90: 30 x 90 / 100 = 27.

Or change the percent to a decimal first, then multiply by the whole number.

E.g. 30% of 90= 0.30 X 90= 27

Remember: the word "OF" in math usually means multiplication!!

How do you find the whole from a percent?

Divide the amount given as a percent of a whole by the percent, converted to a decimal by multiplying the percent by 0.01 (exact). The value of the whole will be the quotient. In symbols, when w is the unknown whole, k is a known percent of the whole, and the percent p itself is known, w = k/(0.01)p or 100 (k/p).
