Writing a ratio as a percent worksheets
A percent is nothing more than a ratio out of a hundred, so writing 3 : 4 as 75% is the same reasoning as an equivalent fraction. These free printable worksheets turn a ratio into a percent, and stay on that one move.

Writing a ratio as a percent
The answer key prints on a separate page.
What's on this sheet
The method is to rescale the ratio so its second term is a hundred: 3 : 4 is the same as 75 : 100, which is 75%. Thinking of it as "how many out of a hundred" is what ties percent back to the equivalent fractions a child already owns, rather than treating it as a new trick with its own rules.
Why this sheet works
Every ratio here is chosen so the percent lands on a whole number — 3 : 4 gives 75%, 1 : 5 gives 20% — so the work is the rescaling and not a long division into decimals. Ratios whose second term does not divide a hundred cleanly are left for later; the aim here is to make the ratio-percent link obvious while the numbers stay friendly.
How this one works
One question from this sheet, worked through a step at a time.
22 : 50 = 44%
22 : 50→▢ : 100
22× 2 =44
22 : 50=44%
- Percent means "out of a hundred", so this is asking what 22 : 50 would be if the second number were 100.
- 50 × 2 = 100, so scale the other side by the same 2: 22 × 2 = 44.
- So 22 out of 50 is 44 out of a hundred — 44%.
