Explicação passo-a-passo:

A)

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

B)

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

C)

$\frac{6}{8} + \frac{3}{2} = \frac{6 + 12}{8} = \frac{18}{8} = \frac{9}{4}$

D)

$\frac{9}{3} + \frac{1}{4} = \frac{36 + 3}{12} = \frac{39}{12} = \frac{13}{4}$
