Explicação passo-a-passo:

$a) \frac{3}{5} + \frac{4}{8} - \frac{2}{4} =$

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

$\frac{3}{5} + 0$

$\frac{3}{5}$

$b) \frac{12}{20} + \frac{5}{10} + \frac{7}{14}$

$\frac{6}{10} + \frac{5}{10} + \frac{7}{14}$

$\frac{6}{10} + \frac{5}{10} + \frac{1}{2}$

$\frac{6 + 5}{10} + \frac{1}{2}$

$\frac{11}{10 } + \frac{1}{2}$

$\frac{11 + 5}{10}$

$\frac{16}{10}$

$\frac{8}{5}$

$c) \frac{7}{3} + \frac{2}{5}$

$\frac{35 + 6}{15}$

$\frac{41}{15}$

$d) \frac{14}{16} + \frac{12}{10}$

$\frac{7}{8} + \frac{12}{10}$

$\frac{7}{8} + \frac{6}{5}$

$\frac{35 + 48}{40}$

$\frac{83}{40}$
