Запишите результат действий.
а) $\frac{3}{5} + \frac{2}{5} =$
б) $\frac{8}{10} - \frac{3}{10} =$
в) $\frac{31}{100} + \frac{31}{100} =$
г) $\frac{29}{30} - \frac{29}{30} =$
д) $\frac{3}{7} + \frac{4}{7} =$
е) $\frac{8}{11} + \frac{2}{11} =$
ж) $\frac{18}{49} - \frac{11}{49} =$
з) $\frac{3}{4} - \frac{2}{4} =$
и) $\frac{8}{8} - \frac{3}{8} =$

$\frac{3}{5} + \frac{2}{5} = \frac{5}{5} = 1$
$\frac{8}{10} - \frac{3}{10} = \frac{5}{10}$
$\frac{31}{100} + \frac{31}{100} = \frac{62}{100}$
$\frac{29}{30} - \frac{29}{30} = 0$
$\frac{3}{7} + \frac{4}{7} = \frac{7}{7} = 1$
$\frac{8}{11} + \frac{2}{11} = \frac{10}{11}$
$\frac{18}{49} - \frac{11}{49} = \frac{7}{49}$
$\frac{3}{4} - \frac{2}{4} = \frac{1}{4}$
$\frac{8}{8} - \frac{3}{8} = \frac{5}{8}$
