# Calculating Percentages

## Parts of 100: Calculating Percentages

Letâ€™s say you scored 85 percent (%) on your last science test. Does that mean you got 85 questions right? Probably not. The score on your test is expressed as a percentage. The word percent comes from Latin words meaning â€œparts of a 100,â€ and thatâ€™s exactly what a percentage is. A percentage is a ratio that compares a number with 100.

PROCEDURE: To find a percentage of a number, first rewrite the percentage you wish to find as a decimal by moving its decimal point two places to the left. Then multiply this decimal number by the number you are finding the percentage of. The result is your percentage.
