Answer 2

1. 5/9 * 4/7 = 20/63
2. 15/17 * 34/45 = 1020/1539 = 340/513 (simplified)
3. 3/7 * 2/5 = 6/35
4. 7/13 * 39/56 = 273/728 = 39/104 (simplified)
5. 3 3/8 * 1 1/15 = (27/8) * (16/225) = 432/1800 = 54/225 (simplified to a mixed number)
6. 3 1/7 * 1 3/11 = (22/7) * (34/121) = 748/847 (simplified)
7. 3 1/9 * 2 1/7 = (28/9) * (15/7) = 140/3 (mixed number simplified)
8. 2 1/7 * 2 4/5 = (15/7) * (14/5) = 42/5 (mixed number simplified)
9. 2 2/5 * 5/24 = (12/5) * (5/24) = 1/4 (simplified to a fraction)
10. 3/8 * 4 4/15 = (3/8) * (64/15) = 256/1200 = 32/150 (simplified to a mixed number)
11. 1 1/9 * 3/10 = (10/9) * (3/10) = 1/3 (mixed number simplified)
12. 4/11 * 4 7/12 = (47/12) * (4/11) = 188/33 (simplified)
