Question

Answer 1

Vou resolver para você. "Sigam-me os bons!!!"

$( \frac{1}{3}+ \frac{1}{2})-( \frac{5}{6}- \frac{3}{4}) \\ \\ ( \frac{1}{3}+ \frac{1}{2}) \\ MMC: 6 \\ \frac{2+3}{6}= \frac{5}{6} \\ \\ ( \frac{5}{6}- \frac{3}{4}) \\ MMC:12 \\ \frac{10-9}{12}= \frac{1}{12}$

Portanto:
$\frac{5}{6}- \frac{1}{12} \\ MMC:12\\ \frac{10-1}{12}= \frac{9}{12}= \frac{3}{4}$

Espero ter ajudado. Valeu!
