Question

4целых7/12-1целая5/12+2целых11/12​

Answer 1

Пошаговое объяснение:

$4 \frac{7}{12} - 1 \frac{5}{12} + 2 \frac{11}{12} = 6 \frac{1}{12}$

$1)4 \frac{7}{12} - 1 \frac{5}{12} = \frac{55}{12} - \frac{17}{12} = \frac{55 - 17}{12}$

$= \frac{38}{12} = \frac{19 \times 2}{6 \times 2} = 3 \frac{1}{6}$

$2)3 \frac{1}{6} + 2 \frac{11}{12} = \frac{19}{6} + \frac{35}{12} = \frac{2 \times 19 + 35}{12} = \frac{73}{12} = 6 \frac{1}{12}$
