Answer 1

resolução!

= 3/9 + 4/12 + 2/3 _____ MMC = 36

= 12 + 12 + 24 / 36

= 48 / 36 ÷ 12

= 4 / 3

resposta : 4/3

Answer 2

$\frac{3 \div 3}{9 \div3} = \frac{1}{3}$

$\frac{4 \div 4}{12 \div 4} = \frac{1}{3}$

$\frac{3}{9} + \frac{4}{12} + \frac{2}{3} \\ = \frac{1}{3} + \frac{1}{3} + \frac{2}{3} = \frac{1 + 1 + 2}{3} = \frac{4}{3}$
