Answer 1

Ответ:

$\frac{2}{45} + \frac{7}{9} =$ $\frac{2}{45} + \frac{35}{45} =$ $\frac{37}{45}$

$\frac{2}{5} + \frac{4}{25}$ $= \frac{10}{25} + \frac{4}{25} =$ $\frac{12}{25}$

$\frac{1}{6} + \frac{7}{18} = \frac{3}{18} + \frac{7}{18} = \frac{10}{18}$

$\frac{19}{42} + \frac{6}{7} = \frac{19}{42} + \frac{36}{42} = \frac{55}{42} = 1\frac{13}{42}$

$\frac{3}{32} + \frac{5}{8} = \frac{3}{32} + \frac{20}{32} = \frac{23}{32}$

$\frac{3}{8} + \frac{1}{56} = \frac{21}{56} + \frac{1}{56} = \frac{22}{56}$
