Question

5 3/8 +9 1/12 -7 5/6​

Answer 1

Пошаговое объяснение:

$1)5 \frac{3}{8} + 9 \frac{1}{12} = \frac{43}{8} + \frac{109}{12} = \frac{3 \times 43 + 2 \times 109}{24} = \frac{347}{24} = 14 \frac{11}{24}$

$2)14 \frac{11}{24} - 7 \frac{5}{6} = \frac{347}{24} - \frac{47}{6} = \frac{347 - 4 \times 47}{24} = \frac{159}{24} = \frac{53 \times 3}{8 \times 3} = 6 \frac{5}{8}$
