Question

Calcule a expressão a seguir:
$( \frac{2}{3} \div \frac{1}{8} ) - \frac{3}{4} + \frac{1}{3} =$
​

Answer 1

Vamos lá..

( 2/3 ÷ 1/8) - 3/4 + 1/3

( 2/3 × 8/1) - 3/4 + 1/3

16/3 - 3/4 + 1/3

64/12 - 9/12 + 4/12

(64-9+4)/12

(55+4)/12

59/12 resposta

Answer 2

Resposta:

$\frac{59}{12}$

Explicação passo-a-passo:

$(\frac{2}{3}\div\frac{1}{8} )-\frac{3}{4}+\frac{1}{3}$

$=(\frac{2}{3}\times\frac{8}{1})-\frac{3\times3}{4\times3}+\frac{1\times4}{3\times4}$

$=\frac{16}{3}-\frac{9}{12}+\frac{4}{12}$

$=\frac{16\times4}{3\times4}-\frac{9}{12}+\frac{4}{12}$

$=\frac{64}{12}-\frac{9}{12}+\frac{4}{12}$

$=\frac{64-9+4}{12}$

$=\frac{59}{12}$
