Question

03) Resolva as expressões à seguir:
a) (2/3 x 6/8) + 1/3 =
b) (1/2 + 3/4) x 5/6 =​

Answer 1

Resposta:

a) 1,5; b)1,04

Explicação passo-a-passo:

a) $(\frac{2}{3} . \frac{6}{8}) + \frac{1}{3} = \frac{12}{24} + \frac{1}{3} = \frac{12 + 24}{24} = \frac{36}{24} = 1,5$

b) $(\frac{1}{2} + \frac{3}{4}) . \frac{5}{6} = (\frac{2+3}{4}) . \frac{5}{6} = \frac{5}{4} . \frac{5}{6} = \frac{25}{24} = 1,04$
