Пошаговое объяснение:
1) 15 : 5/18 = 15 * 18/5 =
3 * 18/1 = 54/1 = 54
2) 54 : 3. 3/8 = 54 : 27/8 =
54 * 8/27 = 2 * 8/1 = 16/1 = 16
3) 1/16 + 11/36 = 9/144 + 44/144 = 53/144
4) 53/144 + 5/48 = 53/144 + 15/144 = 68/144
5) 68/144 + 5/18 = 68/144 + 40/144 = 108/144 = 3/4
6) 16 * 3/4 = 4 * 3/1 = 12/1 = 12
Это числитель
7) 11. 5/11 - 8. 21/22 =
11. 10/22 - 8. 21/22 =
10. 32/22 - 8. 21/22 =
2. 11/22 = 2. 1/2
8) 2. 1/2 : 1. 2/3 =
5/2 : 5/3 = 5/2 * 3/5 = 3/2
Это знаменатель
9) 12 : 3/2 = 12 * 2/3 = 24/3 = 8
