3 1/7×1 2/11+3 3/4:15/28-8 19/42
Пожалуйста, помогите

Answer 1

не особо понял

$\frac{1}{7} \times 1 = \frac{1}{7}$

$\frac{2}{11} + 3 = 66$

$\frac{3}{4} \div \frac{15}{28} - 8 = \frac{3}{4} \times \frac{28}{15} - \frac{8}{1} = \frac{84}{60} - \frac{8}{1} = - \frac{396}{60} = - \frac{132}{20} = \frac{66}{10} = \frac{33}{5}$
