Question

1/2+2/3 ,5/6+2/3,4/5+2/3,9/2+7/4+2/3,

Answer 1

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

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