Answer 1

Пошаговое объяснение:

№7

1) 1/5 * 3 = (1*3)/5 = 3/5

2) 2/11 * 5 = (2*5)/11= 10/11

3) 10 * 1/31 = (10*1)/31 = 10/31

4) 5 * 2/9 = (5*2)/9 = 10/9 = 1 1/9

5) 3 * 3/7 = (3*3)/7 = 9/7 = 1 2/7

№8

1) 7/9 * 6 = (7*6)/9 = 42/9 = 4 6/9 = 4 2/3

2) 4 * 3/20 = (4*3)/20 = 12/20 = 3/5

3) 5/6 * 3 = (5*3)/6 = 15/6 = 2 3/6 = 2 1/2

4) 14 * 7/16 = 7 * 7/8 = (7*7)/8 = 49/8 = 6 1/8

5) 27 * 2/9 = (27*2)/9 = 54/9 = 6
