3,6+4,8*(8 3/4-7 5/6)  8 3\4=35\4  7 5\6 =47\6  35\4-47\6=11\12        4.8=48\10=24\5  24\5*11\12=22\5  3.6=36\10 =18\5
18\5+22\5=8
удачи)

3,6+4,8 * (8 3/4 - 7 5/6 )= 3 3/5 + 4 4/5 *(7 21/12 - 7 10/12)=
=18/5 + 24/5 * 11/12 = 18/5 + 22/5 = 40/5 = 8

Пошаговое объяснение:

. (- 2,5 + 2 1/3) * (- 5 1/7) + 1 1/3 : (- 5,6) = 5/7

1) - 2,5 + 2 1/3 = - 2 5/10 + 2 1/3 = - 2 1/2 + 2 1/3 = - 2 3/6 + 2 2/6 = - 1/6

2) - 1/6 * (-5 1/7) = 1/6 * 36/7 = 6/7

3) 1 1/3 : (- 5,6) = 1 1/3 : (- 5 6/10) = - 1 1/3 : 5 3/5 = - 4/3 : 28/3 = - 4/3 * 3/28 = - 4/28 = - 1/7

4) 6/7 - 1/7 = 5/7

2. - 0,3x + 0,9 = - 4,2;

- 0,3x = - 4,2 - 0,9;

- 0,3 = - 5,1;

x = - 5,1 : (- 0,3);

x = 17.

ответ. 17.

3. - 0,25x + 0.8 = 1,3;

- 0,25x = 1,3 - 0,8;

- 0,25x = 0,5;

x = 0,5 : (- 0,25);

x = - 2.

ответ. - 2.
