Let’s solve each multiplication problem step by step. Remember: when multiplying two fractions, you multiply the numerators (top numbers) together and the denominators (bottom numbers) together. Then simplify if needed — but in this worksheet, all answers are already in simplest form or don’t need simplifying.

We’ll go one by one:

1. 1/5 × 3/5 = (1×3)/(5×5) = 3/25
2. 7/8 × 2/8 = (7×2)/(8×8) = 14/64 → Wait! Let’s check: 14 ÷ 2 = 7, 64 ÷ 2 = 32 → So 7/32? But let’s see what the worksheet expects. Actually, looking at other problems, they may not require simplifying unless it’s obvious. But 14/64 can be simplified to 7/32. However, let’s double-check the pattern — maybe we should leave as is? No, better to simplify. But wait — look at problem 5: 1/3 × 2/3 = 2/9 — that’s already simplified. Problem 8: 2/6 × 2/6 = 4/36 = 1/9. Hmm. Actually, let’s do them correctly and simplify where possible.

But hold on — looking at the worksheet again, many answers are left unsimplified? Let me check problem 10: 1/5 × 4/5 = 4/25 — no simplification needed. Problem 13: 2/3 × 2/3 = 4/9 — fine. Problem 16: 2/4 × 1/4 = 2/16 = 1/8 — so we should simplify.

Actually, to be accurate, I will compute each and simplify fully.

Let’s redo carefully:

1. 1/5 × 3/5 = 3/25
2. 7/8 × 2/8 = 14/64 = 7/32
3. 3/5 × 4/5 = 12/25
4. 6/8 × 3/8 = 18/64 = 9/32
5. 1/3 × 2/3 = 2/9
6. 7/8 × 4/8 = 28/64 = 7/16
7. 3/6 × 4/6 = 12/36 = 1/3
8. 2/6 × 2/6 = 4/36 = 1/9
9. 2/5 × 3/5 = 6/25
10. 1/5 × 4/5 = 4/25
11. 4/8 × 6/8 = 24/64 = 3/8
12. 4/6 × 4/6 = 16/36 = 4/9
13. 2/3 × 2/3 = 4/9
14. 1/6 × 5/6 = 5/36
15. 2/8 × 4/8 = 8/64 = 1/8
16. 2/4 × 1/4 = 2/16 = 1/8
17. 1/3 × 1/3 = 1/9
18. 6/8 × 7/8 = 42/64 = 21/32
19. 4/5 × 2/5 = 8/25
20. 1/5 × 5/5 = 5/25 = 1/5
21. 1/6 × 4/6 = 4/36 = 1/9
22. 3/4 × 3/4 = 9/16
23. 5/8 × 1/8 = 5/64
24. 4/5 × 1/5 = 4/25
25. 5/8 × 5/8 = 25/64
26. 2/8 × 5/8 = 10/64 = 5/32
27. 3/6 × 3/6 = 9/36 = 1/4
28. 2/4 × 2/4 = 4/16 = 1/4
29. 3/6 × 5/6 = 15/36 = 5/12
30. 7/8 × 3/8 = 21/64

Wait — let me verify a few that might be tricky:

Problem 7: 3/6 × 4/6 → 3×4=12, 6×6=36 → 12/36 = 1/3 ✔️
Problem 8: 2/6 × 2/6 = 4/36 = 1/9 ✔️
Problem 11: 4/8 × 6/8 = 24/64 → divide numerator and denominator by 8 → 3/8 ✔️
Problem 15: 2/8 × 4/8 = 8/64 = 1/8 ✔️
Problem 16: 2/4 × 1/4 = 2/16 = 1/8 ✔️
Problem 20: 1/5 × 5/5 = 5/25 = 1/5 ✔️
Problem 21: 1/6 × 4/6 = 4/36 = 1/9 ✔️
Problem 26: 2/8 × 5/8 = 10/64 = 5/32 ✔️
Problem 27: 3/6 × 3/6 = 9/36 = 1/4 ✔️
Problem 28: 2/4 × 2/4 = 4/16 = 1/4 ✔️
Problem 29: 3/6 × 5/6 = 15/36 → divide by 3 → 5/12 ✔️

All seem correct.

Now, listing all final answers in order:
