a)

 \frac{1}{2} + \frac{2}{3}

mmc = 6

 \frac{3+4}{6} = \frac{7}{6}

b)

 \frac{5}{6} + \frac{2}{3}

mmc = 6

 \frac{5+4}{6} = \frac{9}{6} = \frac{3}{2}

c)

 \frac{4}{5} + \frac{2}{3}

mmc = 15

 \frac{12+10}{15} = \frac{22}{15}

d)

 \frac{9}{2} + \frac{7}{4} + \frac{2}{3}

mmc = 12

 \frac{54+21+8}{12} = \frac{84}{12} =7
