Question

Alguém pra me ajudar?

Answer 1

parte de cima
$\frac{1}{6} - \frac{1}{3} = mmc \: = 6 \\ \\ \frac{6}{6} - \frac{2}{6} = \frac{4}{6} \\ \\ \ \frac{1}{1} - \frac{4}{6} = mmc = 6 \\ \\ \frac{6}{6} - \frac{4}{6} = \frac{2}{6}$
parte de baixo
$\frac{1}{6} + \frac{1}{2} = mmc = 6 \\ \\ \frac{6}{6} + \frac{3}{6} = \frac{3}{6} \\ \\ (\frac{3}{6}) {}^{2} = \frac{9}{36} \\ \\ \frac{9}{36} + \frac{3}{2} = mmc = 36 \\ \\ \frac{9}{36} + \frac{54}{36} = \frac{63}{36}$
resultado final
$\frac{2}{6} \div \frac{63}{36} \\ inverte \: e \: multiplica \\ \frac{2}{6} \times \frac{36}{63} = \frac{72}{378} = simplifica \\ \frac{72 \div 2}{378 \div 2} = \frac{36 \div 3}{189 \div 3} = \frac{12 \div 3}{63 \div 3} = \frac{4}{21}$
