5 1/16 - 1 1/8 * (5/6 + 3/14)
Помогите

Answer 1

Ответ:

$\frac{31}{6} - \frac{9}{8} \times ( \frac{5 \times 7 + 3 \times 3}{42} ) = \frac{31}{6} - \frac{9}{8 }\times \frac{44}{42} = \frac{31}{6} - \frac{9 \times 22}{8 \times 21} = \frac{31}{6} - \frac{3 \times 11}{4 \times 7} = \frac{31}{6} - \frac{33}{28} = \frac{31 \times 14 + 33 \times 3}{8} = \frac{335}{84} = 3 \frac{83}{84}$
