Answer 1

Ответ:

$-1\frac{5}{24}$

Пошаговое объяснение:

$2\frac{5}{8}-3\frac{5}{6}=\frac{2*8+5}{8}-\frac{3*6+5}{6}=\frac{21}{8}-\frac{23}{6}=\frac{21*6}{8*6}-\frac{23*8}{6*8}=\frac{126}{48}-\frac{184}{48}=\frac{126-184}{48}=-\frac{58}{48}=-\frac{29}{24}=-1\frac{5}{24}$

Answer 2

$2 \frac{5}{8} - 3 \frac{5}{6} = 2 \frac{15}{24} - 3 \frac{20}{24} = -1 \frac{5}{24}$
