Certainly! This worksheet asks you to multiply a decimal number with
one decimal place (like 1.4, 2.1, etc.) by a single-digit whole number:
2, 3, 4, or 5.

✔ Key Rule for Multiplying Decimals:
> When multiplying a decimal by a whole number, ignore the decimal point at first. Multiply as if both numbers were whole numbers. Then, count the number of decimal places in the original decimal number and place the decimal point in the answer so that it has the same number of decimal places.
Since all decimals here have
1 decimal place, your final answer should also have
1 decimal place.

Let’s solve each problem step-by-step:
---
1) 1.4 × 3
→ 14 × 3 = 42 → Place decimal:
4.2

3) 4.3 × 2
→ 43 × 2 = 86 →
8.6
4) 1.6 × 5
→ 16 × 5 = 80 →
8.0 (or just
8, but since we need 1 decimal place, write
8.0)
