Math worksheet for practicing multiplication of fractions by whole numbers.

Let’s solve each problem step by step. We’re multiplying fractions by whole numbers.

Rule: To multiply a fraction by a whole number, multiply the numerator (top number) by the whole number. Keep the denominator (bottom number) the same. Then simplify if possible.

Left Column:

1. 2/9 × 3
→ 2 × 3 = 6 → 6/9
→ Simplify: divide top and bottom by 3 → 2/3

2. 9/8 × 2
→ 9 × 2 = 18 → 18/8
→ Simplify: divide by 2 → 9/4 → or as mixed number: 2 1/4

3. 3/14 × 8
→ 3 × 8 = 24 → 24/14
→ Simplify: divide by 2 → 12/7 → or 1 5/7

4. 6/15 × 9
→ 6 × 9 = 54 → 54/15
→ Simplify: divide by 3 → 18/5 → or 3 3/5

5. 8/24 × 7
→ First simplify 8/24 → divide by 8 → 1/3
→ 1/3 × 7 = 7/3 → or 2 1/3

6. 6/18 × 5
→ Simplify 6/18 → divide by 6 → 1/3
→ 1/3 × 5 = 5/3 → or 1 2/3

7. 7/32 × 8
→ 7 × 8 = 56 → 56/32
→ Simplify: divide by 8 → 7/4 → or 1 3/4

8. 4/14 × 6
→ Simplify 4/14 → divide by 2 → 2/7
→ 2/7 × 6 = 12/7 → or 1 5/7

Right Column:

9. 5/12 × 9
→ 5 × 9 = 45 → 45/12
→ Simplify: divide by 3 → 15/4 → or 3 3/4

10. 4/35 × 7
→ 4 × 7 = 28 → 28/35
→ Simplify: divide by 7 → 4/5

11. 5/8 × 4
→ 5 × 4 = 20 → 20/8
→ Simplify: divide by 4 → 5/2 → or 2 1/2

12. 6/32 × 4
→ Simplify 6/32 → divide by 2 → 3/16
→ 3/16 × 4 = 12/16 → simplify → 3/4

13. 6/16 × 5
→ Simplify 6/16 → divide by 2 → 3/8
→ 3/8 × 5 = 15/8 → or 1 7/8

14. 8/36 × 6
→ Simplify 8/36 → divide by 4 → 2/9
→ 2/9 × 6 = 12/9 → simplify → 4/3 → or 1 1/3

15. 3/21 × 7
→ Simplify 3/21 → divide by 3 → 1/7
→ 1/7 × 7 = 1

16. 8/18 × 2
→ Simplify 8/18 → divide by 2 → 4/9
→ 4/9 × 2 = 8/9
