2−2/7=
4 3/5 - 1 2/15 =
3−2 1/3=
12 14/13−5 10/13=
(3+ 4/7)−2=

Answer 1

Пошаговое объяснение:

2−2/7=1 7/7 - 2/7 = 1 5/7

4 3/5 - 1 2/15 = 4 9/15 - 1 2/15 = 3 7/15

3−2 1/3=2 3/3 - 2 1/3 = 2/3

12 14/13−5 10/13=7 4/13

(3 + 4/7)−2=1 4/7

Answer 2

$2 - \frac{2}{7} = 1 \frac{7}{7} - \frac{2}{7} = 1 \frac{7 - 2}{7} = 1 \frac{5}{7}$

$4 \frac{3}{5} - 1 \frac{2}{15} = 4 \frac{9}{15} - 1 \frac{2}{15} = 3\frac{7}{15}$

$3 - 2 \frac{2}{15} = 2 \frac{3}{3} - 2 \frac{1}{3} = 2 \frac{3}{3 } = \frac{3- 1}{3} = \frac{2}{3}$

$(3 + \frac{4}{7} ) - 2 =1 \frac{4}{7}$

$(3 + \frac{4}{7} ) - 2 =1 \frac{4}{7}$
