Question

Resolva 1/2 - 1/3 - 1/6

Answer 1

$\frac{1}{2}$ - $\frac{1}{3}$ - $\frac{1}{6}$ = $\frac{-1}{-7}$

Answer 2

$\frac{1}{2} \frac{3}{3} - \frac{1}{3} - \frac{1}{6}$

$\frac{1}{2} \frac{3}{3} - \frac{1}{3} \frac{2}{2} - \frac{1}{6}$

$\frac{1*3}{6}- \frac{1*2}{6} - \frac{1}{6}$$\frac{1}{6} - \frac{1}{6} = 0$
