Answer 1

Resposta:

6/11

7/15

63/62

3/14

2/15

4/15

Explicação passo-a-passo:

8/11 - 2/11 = 6/11

3/15 + 4/15 = 7/15

21/31 ÷ 2/3 = 21/31 x 3/2 = 63/62

1/7 ÷ 2/3 = 1/7 x 3/2 = 3/14

2/5 x 1/3 = 2/15

4/9 x 3/5 = 12/45 :(3) = 4/15

Answer 2

8/11 - 2/11 = 6/11

3/15 + 4/15 = 7/15

21/31 ÷ 2/3 = 63/62

1/7 ÷ 2/3 = 3/14

2/5 × 1/3 = 2/15

4/9 × 3/5 = 4/15

Espero ajudar.
