Answer:
12. 3/4 * 7/8 is < 7/8
13. 4/3 * 3/8 = 1/2
14. 3/5 * 1/6 = 3/10
15. 1/3 * 4/5 < 4/5
Explanation:
12. 3/4 * 7/8 is <, >, or =, 7/8
3/4 * 7/8 ? 7/8
21/32 ? 7/8
21/32 ? 28/38
21/32 < 28/32
13. 4/3 * 3/8 is <, >, or =, 1/2
4/3 * 3/8 ? 1/2
12/24 ? 1/2
12/24 ? 12/24
12/24 = 12/24 (1/2)
14. 3/5 * 1/6 is <, >, or =, 1/10
3/5 * 1/6 ? 1/10
3/30 ? 1/10
3/30 ? 3/30
3/30 = 3/30 (1/3)
15. 1/3 * 4/5 is <, >, or =, 4/5
1/3 * 4/5
4/15 ? 4/5
4/15 ? 12/15
4/15 < 12/15 (4/5)
Hope this helps!
