Comparing decimals worksheets

Comparing decimals catches the classic trap — thinking 0.45 is bigger than 0.5 because it has more digits. These free printable worksheets drill the place-value comparison that fixes it.

Comparing decimals worksheet — Tenths to thousandths, free printable with answer key

The answer key prints on a separate page.

What's on this sheet

The child writes the greater-than, equals, or less-than sign between two decimals. Pairs run to thousandths and often differ in length (0.7 and 0.65), and some are equal written two ways (0.5 = 0.50) — exactly the trailing-zero idea the skill is really about. Comparison is done by place value, never by counting digits.

Why this sheet works

Choose tenths, hundredths, or thousandths for the difficulty.

How this one works

One question from this sheet, worked through a step at a time.

7.21 ? 6.05

7.21?6.05
7.21?6.05
721 hundredths>605 hundredths
7.21>6.05
  1. Both have 2 figures after the point already, so they are counting the same sized pieces.
  2. Now they are both hundredths: 721 against 605. 721 is more. So 7.21 > 6.05.
