Answer 2

Ответ:

Пошаговое объяснение:

$\displaystyle\\\[\frac{1}{2} + \frac{1}{4} + \frac{3}{8} = \frac{4}{8} + \frac{2}{8} + \frac{3}{8} = \frac{9}{8} = 1\frac{1}{8}\]$

$\displaystyle\\\[\frac{3}{4} + \frac{5}{6} + \frac{1}{2} = \frac{9}{{12}} + \frac{{10}}{{12}} + \frac{6}{{12}} = \frac{{25}}{{12}} = 2\frac{1}{{12}}\]$

$\displaystyle\\\[\frac{4}{5} + \frac{4}{{15}} + \frac{3}{{10}} = \frac{{24}}{{30}} + \frac{8}{{30}} + \frac{9}{{30}} = \frac{{41}}{{30}} = 1\frac{{11}}{{30}}\]$

$\displaystyle\\\[\frac{3}{8} + \frac{5}{6} + \frac{7}{{12}} = \frac{9}{{24}} + \frac{{20}}{{24}} + \frac{{14}}{{24}} = \frac{{43}}{{24}} = 1\frac{{19}}{{24}}\]$
