Watch: Long Division With Decimals Step by Step

Key idea

Multiply: 3.02 × 1.5 → 302 × 15 = 4530; three decimal places → 4.53. Divide: 18.9 ÷ 3.5 → shift both one place → 189 ÷ 35 = 5.4.

Sample problems

Compute 0.3 × 0.7.
Compute 2.4 × 0.5.
Compute 12.6 × 3.
Compute 4.05 × 2.6.

Common mistakes to watch for

Answered 2.4 (counted only one place) or 0.024 (counted three). Count the places in BOTH factors and add.
Placed the point by lining up the factors instead of counting places → 45.5 or 0.455.
Dropped the decimal point entirely → 24.

The answer key explains each one, so you can tell what a wrong answer means.
