Learn it Compare decimals place by place after lining up the points (add zeros so they have the same number of places). Round decimals the same way as whole numbers.

Example: Round 12.647 to the nearest tenth.

The tenths digit is 6. The next digit (hundredths) is 4.
4 is less than 5, so round down.
12.647 ≈ 12.6.
