Answer 1

Ответ:

$1) \frac{13 - 69}{42} \div \frac{56}{6} \times \frac{7}{4} = - \frac{1}{4} \\ 1) \frac{13 - 69}{42} \div \frac{56}{6} = \\ = \\ - \frac{56}{42} \times \frac{6}{56} = - \frac{1}{7} \\ 2) - \frac{1}{7} \times \frac{7}{4} = - \frac{1}{4}$

2)

$\frac{ - 9.2 + 4.7}{1.8} = - \frac{4.5}{1.8} = - \frac{45}{18} = - 2 \frac{9}{18} = - \\ = - 2 \frac{1}{2}$
