How do I read this chart?

Find the fraction, read across: 3/4 is 75%, 3/8 is 37.5%. Percent is the same number written in hundredths, so the decimal column is the bridge between them.

What are the most common fraction–percent pairs?

The ones worth memorizing: 1/2 = 50%, 1/4 = 25%, 3/4 = 75%, 1/5 = 20%, 1/8 = 12.5%, and 1/3 ≈ 33.33% — that last one repeating, never exact in digits.

Fraction → percent chart

The everyday fractions read as percentages. Exact values print plainly; repeating ones are rounded and marked ≈.
