(-2 3/8 - 1 5/6) : ( 1 5/8) найти значения выражения

Answer 1

$( - 2 \frac{3}{8} - 1 \frac{5}{6} ) \div 1 \frac{5}{8} = - 2 \frac{23}{29} \\ - 2 \frac{3}{8} - 1 \frac{5}{6} = - 2 \frac{9}{24} - 1 \frac{20}{24} = - 3 \frac{29}{24} = - 4 \frac{5}{24} \\ - 4 \frac{5}{24} \div 1 \frac{5}{8} = - \frac{101 \times 8}{24 \times 13} = - \frac{101 \times 1}{3 \times 13} = \\ - \frac{101}{39} = - 2 \frac{23}{29}$
