Answer 1

7/8-1/4+5/12= 21-6+10/24= 25/24 = 1 1/24.

Answer 2

Пошаговое объяснение:

$1) \frac{7}{8} - \frac{1}{4} = \frac{7 \times 1}{8 \times 1} - \frac{1 \times 2}{4 \times 2} = \frac{7}{8} - \frac{2}{8} = \frac{7 - 2}{8} = \frac{5}{8}$

$2)\frac{5}{8} + \frac{5}{12} = \frac{5 \times 3}{8 \times 3} + \frac{5 \times 2}{12 \times 2} = \frac{15}{24} + \frac{10}{24} = \frac{15 + 10}{24} = \frac{25}{24} = \frac{1 \times 24 + 1}{24} = 1 \frac{1}{24}$
