помогите решить примеры

Answer 1

$( \frac{8}{9} + \frac{4}{5} ) \times 7 = \frac{76}{45} \times 7 = \frac{532}{45}$

$( \frac{8}{11} - \frac{1}{22} ) \times 4 = \frac{17}{22} \times 4 = \frac{17}{11} \times 2 = \frac{34}{11}$

$(\frac{4}{7} + \frac{3}{4} ) \times 3 = \frac{37}{28} \times 3 = \frac{111}{28}$
