Answer 1

Multiplicación:

1) 3 × 7/ 5 × 4 = 21/20

2) 4/3 × 8/3 = 4 × 8/3 × 3 = 32/9

3) 2/3 × 3/2 = 1/3 × 3 = 1

4) 7/3 × 11/4 = 7 × 11/3 × 4 = 77/12

5) 1/2 × 30/7 = 15/7

División:

1) - 4/5 × 20/10 = - 5/4 × 2 = - 5/2

2) 6/2 × 10/21 = - 3 × 10/21 = - 10/7

3) 16/8 × 4/10 = 2 × 4/10 = 2 × 2/5 = 2/1 × 2/5 = 2 × 2/1 × 5 = 4/5

4) - 13/7 × 8/7 = - 13 × 8/7 × 7 = - 104/49

5) 16/8 × 1/8 = 2 × 1/8 = 1/4
