How percentages are calculated
A percentage expresses a part per hundred. To find a percentage of an amount, multiply the amount by the percentage and divide by one hundred. To find what percent one number is of another, divide the part by the whole and multiply by one hundred. The formula and a worked example appear under each mode.
