Multiplying Decimals Less Than 1 (Tenths × Tenths) — Easy Worksheet 2
Grade 5 · MathSheets Name: ____________________ Date: __________
Answer each question. The same kind of product comes in different shapes. Write zeros in front if you need more decimal places.
How to solve
Multiply the digits as whole numbers (0.3 × 0.7 → 3 × 7 = 21). Add the decimal places of both factors (1 + 1 = 2) and give the answer that many: 0.21. If there are not enough digits, write zeros in front: 0.04 × 0.2 → 4 × 2 = 8, 3 places → 0.008.
Example
0.2 × 0.6 = ___
Answer: 0.12
Warm-up

💡 Multiply as whole numbers: 9 × 3 = 27. 0.9 has 1 decimal place and 0.3 has 1 decimal place, so the product has 2: 0.27.
✓ Correct!

Picture it
Not quite. The answer is
💡 The dark squares make a rectangle 9 columns wide and 8 rows tall: 9 × 8 = 72 squares. Each square is 0.01, so 72 hundredths is 0.72. So 0.9 × 0.8 = 0.72.
✓ Correct!
