Answer 1

Ответ:

$- \frac{1}{3}$

Объяснение:

$( \frac{7}{16} - ( - \frac{5}{24} )) \div ( - 1 \frac{15}{16} ) = ( \frac{7}{16} + \frac{5}{24} ) \div ( - \frac{31}{16} ) = ( \frac{21}{48} + \frac{10}{48} ) \div ( - \frac{31}{16} ) = \frac{31}{48} \div ( - \frac{31}{16} ) = - \frac{31 \times 16}{48 \times 31} = - \frac{1}{3}$
