Выполните деление 3/4:9, 2/5:10, 11/15:22, 4/7:2, 2 1/7:15, 1 7/9:8, 4 1/2:6, 5 1/7:7

Решение: при делении дробей используем правило (x/y) / (n/m) = x/y*m/n = (x*m) / (y*n)

3/4:9 = (4/4) / (9/1) = (3*1) / (4*9) = 3/36=1/12

2/5:10 = (2/6) / (10/1) = (2*1) / (5*10) = 2/50=1/25

11/15:22 (11/15) / (22/1) = (11*1) / (15*22) = 11/330=1/30

4/7:2 = (4/7) / (2/1) = (4*1) / (7*2) = 4/14=2/7

2 1/7:15 = (15/7) / (15/1) = (15*1) / (7*15) = 1/7

1 7/9:8 = (16/9) / (8/1) = (16*1) / (9*8) = 2/0

4 1/2:6 = (9/2) / (6/1) = (9*1) / (2*6) = 9/12=3/4

5 1/7:7 = (36/7) / (7/1) = (36*1) / (7*7) = 36/49
