Question

Вычислите 2/7+3/8; 5/6-4/9; 3*1/8+2*5/6

Answer 1

1) $\frac{37}{56}$; 2) $\frac{7}{18}$; 3) $1\frac{19}{24}$.

Пошаговое объяснение:

$\frac{16}{56} +\frac{21}{56} = \frac{16+21}{56} =$$\frac{37}{56}$$\frac{5}{6}-\frac{4}{9}=$$\frac{15}{18}-\frac{8}{18}=$$\frac{7}{18}$

$\frac{3*1}{8} + \frac{2*5}{6} =$  $\frac{3}{8} + \frac{2*5}{6} =$  $\frac{3}{24} + \frac{40}{24} =$$\frac{43}{24} =$$1\frac{19}{24}$
