1) 28 : 1 3/4 = 28 : 7/4 = 16
2) 7 1/3 : 22 = 22/3 : 22 = 1/3
3) 1 2/3 * 9 3/4 = 5/3 * 39/4 = 65/4 = 16,25
4) 14 : 1 1/2 = 14 : 3/2 = 28/3
5) 16 + 1/3 + 16,25 + 28/3 = 32,25 + 29/3 = 32 1/4 + 29/3 = 129/4 + 29/3 =
= 387/12 + 116/12 = 503/12
6) 503/12 * 3 1/7 = 503/12 * 22/7 = 11066/84 = 5533/42 = 131 31/42
Ответ 131 целая 31/42
