Question

Упростить выражение
1/6(4a-2)-1/5(5b+6) ​

Answer 1

Пошаговое объяснение:

1/6(4a - 2) - 1/5(5b + 6) =

= 1/6 * 4a - 1/6 * 2 - 1/5 * 5b - 1/5 *

* 6 = 4/6a - 2/6 - b - 6/5 =

= 4/6a - 1/3 - b - 6/5 =

= 4/6a - b - 23/15 = 4/6a - b - 1 8/15

Answer 2

Ответ:

$\frac{2}{3}a-b-1\frac{8}{15}$

Пошаговое объяснение:

$\displaystyle \frac{1}{6}(4a-2)-\frac{1}{5}(5b+6)=\frac{1}{6}\cdot 4a-\frac{1}{6}\cdot 2-\frac{1}{5}\cdot 5b-\frac{1}{5}\cdot 6=\\\\\frac{2}{3}a-\frac{1}{3}-b-\frac{6}{5}=\frac{2}{3}a-\frac{5}{15}-b-\frac{18}{15}=\\\\\frac{2}{3}a-b-\frac{23}{15}=\frac{2}{3}a-b-1\frac{8}{15}$
