Question

(1/2 -1/3) + ( 1/4-2/3) . 2/5

Answer 1

Explicação passo a passo:

$\left(\frac{1}{2}-\frac{1}{3}\right)+\left(\frac{1}{4}-\frac{2}{3}\right).\frac{2}{5}\\\\\frac{1}{6}+\left(\frac{1}{4}-\frac{2}{3}\right)\frac{2}{5}\\\\\\\frac{1}{6}-\frac{5}{12}\cdot \frac{2}{5}\\\\\frac{1}{6}-\frac{1}{6}=0$
