1/3+4/3
5-6/7​

Answer 1

Ответ:

$\frac{3}{7} + \frac{2}{7} = \frac{5}{7} \\ \frac{1}{3} + \frac{4}{3} = \frac{5}{3} \\ 5 - \frac{6}{7} = 4 \frac{7}{7} - \frac{6}{7} = 4 \frac{1}{7}$

Answer 2

Ответ:

$\frac{3}{7} + \frac{2}{7} = \frac{5}{7}$

$\frac{1}{3} + \frac{4}{3} = \frac{5}{3} = 1\frac{2}{3}$

$5 - \frac{6}{7} = \frac{5}{1} - \frac{6}{7} = \frac{35}{7} - \frac{6}{7} = \frac{29}{7} = 4\frac{1}{7}$
