Question

Expressão numérica com fração

Answer 1

Resposta:

Explicação passo a passo:

a)

1/2 + 2/3 = 7/6

5/6 + 2/3 = 3/2

7/6 : 3/2 = 7/6 * 2/3 = 14/18 = 7/9

b)

4/5 + 2/3 = 22/15

1/2 - 1/3 = 1/6

22/15 : 1/6 = 22/15 * 6 = 44/5

c)

5/4 - 1/2 = 3/4

2/5 + 1/10 = 1/2

3/4 : 1/2 = 3/4 * 2 = 6/4 = 3/2

d)

1/4 * 3/7 = 3/28

1/4 + 1/5 = 9/20

3/28 : 9/20 = 3/28 * 20/9 = 30/252 = 5/42

e) 9/2 : 2/6 = 9/2 * 6/2 = 54/4 = 27/2
