Пошаговое объяснение:

Answer 2

1. (3/10) * (5/7) = 15/70 = 3/14
2. (7/12) * (4/5) * (1/7) = 28/420 = 1/15
3. (1/5) * 25 = 25/5 = 5
4. (5/12) * (36/11) * (7/9) = 1260/594 = 70/33
5. (24) * (7/12) = 168/12 = 14
6. (3/8) * (4/5) = 12/40 = 3/10
7. (5/12) * (54/11) * (7/9) = 1890/594 = 105/33
8. (1/10) * (11/15) = 11/150
9. (3) * (2/9) = 6/9 = 2/3
10. (1/5) * (7/15) = 7/75
11. (2/7) * (3) = 6/7
12. (9/10) * (9/14) * (5/7) = 405/980 = 9/28
13. (8/15) * (3/11) * (5/12) = 120/1980 = 2/33
14. (5/9) * (54) = 270/9 = 30
15. (3/14) * (7/12) = 21/168 = 1/8
