Answer 1

letra a

$\frac{1}{2} + \frac{5}{6} = \frac{3 + 5}{6} = \frac{8 \div 2}{6 \div 2} = \frac{4}{3}$

letra b

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

letra c

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

letra d

$\frac{1}{3} + \frac{5}{6} = \frac{2 + 5}{6} = \frac{7}{6}$

letra e

$\frac{2}{5} - \frac{3}{10} = \frac{4 - 3}{10} = \frac{1}{10}$

letra f

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