Answer 2

Explicação passo a passo:

a) MMC: 4

$\frac{5}{2} + \frac{3}{4} = \frac{10}{4} + \frac{3}{4} = \frac{13}{4}$

b) MMC: 6

$\frac{3}{2} + \frac{7}{3} = \frac{9}{6} + \frac{14}{6} = \frac{23}{6}$

c) MMC: 8

$\frac{6}{8} + \frac{3}{2} = \frac{6}{8} + \frac{12}{8} = (\frac{18}{8})^{:2} = \frac{9}{4}$

d) MMC: 12

$\frac{9}{3} + \frac{1}{4} = \frac{36}{12} + \frac{3}{12} = (\frac{39}{12})^{:3} = \frac{13}{4}$
