I'll solve the fraction multiplication problems shown in the image. Let me work through each problem step by step.
First, let me look at the example provided at the top:
1/2 × 4/5 = 4/10 (which can be simplified to 2/5)
3/4 × 2/3 = 6/12 (which can be simplified to 1/2)
Now I'll solve each of the problems in the worksheet:
1. 1/4 × 2/3 = (1×2)/(4×3) = 2/12 = 1/6
2. 3/8 × 2/3 = (3×2)/(8×3) = 6/24 = 1/4
3. 2/5 × 3/4 = (2×3)/(5×4) = 6/20 = 3/10
4. 1/4 × 3/5 = (1×3)/(4×5) = 3/20
5. 3/4 × 1/6 = (3×1)/(4×6) = 3/24 = 1/8
6. 3/4 × 2/9 = (3×2)/(4×9) = 6/36 = 1/6
7. 3/5 × 2/3 = (3×2)/(5×3) = 6/15 = 2/5
8. 2/3 × 3/8 = (2×3)/(3×8) = 6/24 = 1/4
9. 2/3 × 1/6 = (2×1)/(3×6) = 2/18 = 1/9
10. 3/4 × 1/3 = (3×1)/(4×3) = 3/12 = 1/4
11. 3/4 × 2/5 = (3×2)/(4×5) = 6/20 = 3/10
12. 1/2 × 3/4 = (1×3)/(2×4) = 3/8
13. 2/3 × 1/4 = (2×1)/(3×4) = 2/12 = 1/6
14. 1/6 × 2/3 = (1×2)/(6×3) = 2/18 = 1/9
15. 3/4 × 2/3 = (3×2)/(4×3) = 6/12 = 1/2
16. 1/3 × 1/2 = (1×1)/(3×2) = 1/6
17. 3/8 × 2/3 = (3×2)/(8×3) = 6/24 = 1/4
18. 3/4 × 2/3 = (3×2)/(4×3) = 6/12 = 1/2
The solutions are:
1/6, 1/4, 3/10, 3/20, 1/8, 1/6, 2/5, 1/4, 1/9, 1/4, 3/10, 3/8, 1/6, 1/9, 1/2, 1/6, 1/4, 1/2
