Fraction, decimal and percent — the same thing in three forms

A fraction, a decimal and a percent are three ways of writing the same idea — a part of one whole. This exercise drills the friendly equivalences you should know by heart: 1/2 = 0.5 = 50 %, 1/4 = 0.25 = 25 %, 1/10 = 0.1 = 10 %, and so on.

What does this generator do?

Picks one of the common fractions (1/2, 1/4, 3/4, 1/5, 2/5, 3/5, 4/5, 1/10, 3/10, 7/10, 9/10, 1/100, 1/1) and asks you to convert to a percentage, or vice versa.

How to use it

Fraction → percent: divide the top by the bottom, multiply by 100. Decimal → percent: shift the decimal point two places right (0.25 → 25). Percent → decimal: shift two places left (40 % → 0.40).
