Espero que esteja claro, bom dia ;))

Answer 2

$a)\frac{2}{3} + \frac{1}{15} = \frac{10}{15} + \frac{1}{15} = \frac{11}{15}$

$b)\frac{12}{8} - \frac{3}{4} = \frac{12}{8} - \frac{6}{8} = \frac{6}{8} = \frac{3}{4}$

$c) \frac{2}{7} + \frac{1}{14} = \frac{4}{14} + \frac{1}{14} = \frac{5}{14}$

$d) \frac{1}{2} - \frac{5}{12} = \frac{6}{12} - \frac{5}{12} = \frac{1}{12}$

$e) \frac{7}{9} + \frac{1}{3} = \frac{7}{9} + \frac{3}{9} = \frac{10}{9}$

$f) \frac{5}{6} - \frac{2}{3} = \frac{5}{6} - \frac{4}{6} = \frac{1}{6} ok$
