Answer 1

ответом является - 1/4

Answer 2

$\frac{37}{48} \div (5 + \frac{2}{7} ) - \frac{19}{42} \times \frac{7}{8} = - \frac{1}{4} \\ 1)5 + \frac{2}{7} = 5 \frac{2}{7}$

$2) \frac{37}{48} \div 5 \frac{2}{7} = \frac{37}{48} \div \frac{37}{7} = \\ = \frac{37}{48} \times \frac{7}{37} = \frac{7}{48}$

$3) \frac{19}{42} \times \frac{7}{8} = \frac{19}{48}$

$4) \frac{7}{48} - \frac{19}{48} = - \frac{12}{48} = - \frac{1}{4}$
