Пошаговое объяснение:
16 : 4/5 = 16 * 5/4 = 4 * 5/1 = 20/1 = 20
15 : 3/4 = 15 * 4/3 = 5 * 4/1 = 20/1 = 20
2 3/4 : 7/8 = 11/4 * 8/7 = 11/1 * 2/7 = 22/7 = 3 1/7
Ответ:
16 - 4/5
х - 1
х = 16 : 4/5 = 16 * 5/4 = 80/4 = 20
15 - 3/4
х= 15 : 3/4 = 15 * 4/3 = 60/3 = 20
7/8 - 2 3/4
1 - х
х = 2 3/4 : 7/8 = 11/4 * 8/7 = 22/7 = 3 1/7
