Best Answer

Take the number you have out of the whole, then dived it by the whole number. Multiply the resulting number by 100 and that's your percent.

Example:

What percentage is 7 of 10?

7 / 10= .7

.7 x 100 = 70

7 is 70% of 10.

Divide (the known part) by (the percent). The quotient is the whole unknown number.

Divide the percent into 100 then multiply the result by the number that is that percent of the whole. For example, if 25% of your weekly wage is $65, then... 100 divided by 25 is 4. 4 times $65 = $260.

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).

To find a percentage in a whole number, multiply the number by 100%, or put two zeroes and a percent sign after the number.
