Answer 1

a)

$\frac{1}{2} + \frac{5}{6}$

$\frac{3 + 5}{6} = \frac{8}{6} = \frac{4}{3}$

b)

$\frac{3}{4} - \frac{1}{2}$

$\frac{3 - 2}{4} = \frac{1}{4}$

c)

$\frac{5}{6} - \frac{1}{3}$

$\frac{5 - 2}{6} = \frac{3}{6} = \frac{1}{2}$

d)

$\frac{2}{5} - \frac{3}{10}$

$\frac{4 - 3}{10} = \frac{1}{10}$

e)

$\frac{1}{3} + \frac{1}{6}$

$\frac{2 + 1}{6} = \frac{3}{6} = \frac{1}{2}$
