📚 How to Multiply Decimals

The 3-Step Method

1
Ignore the decimal points and multiply as if they were whole numbers.
2.3 × 1.4 → multiply 23 × 14 = 322
2
Count the total decimal places in BOTH numbers.
2.3 has 1 place, 1.4 has 1 place → total = 2 places
3
Place the decimal point that many places from the right in your answer.
322 → move 2 places → 3.22

Decimal Places Quick Guide

0.3 → 1 decimal place
0.25 → 2 decimal places
0.125 → 3 decimal places

Add up all the decimal places from both numbers — that tells you where the decimal goes in the answer.

Quick Examples

0.6 × 0.4 = 0.24
5 × 0.3 = 1.5
1.2 × 1.5 = 1.80
