(3,5- 3 1/3)*(-4 5/4)+ 2 1/3:(-2,8)=

решить:(

-1 7/8

Пошаговое объяснение:

-(35/10-10/3)*25/4-7/3*(10/28)=

-(7/2-10/3)*25/4-10/12=

-(1/6)*25/4-5/6=-25/24-20/24=

-45/24=-15/8=-1 7/8

Пошаговое объяснение:

1) 3,5 - 3. 1/3 = 3. 5/10 - 3. 1/3 = 3. 15/30 - 3. 10/30 = 5/30 = 1/6

2) 1/6 * (-4. 5/4) = 1/6 * (-21/4) = -21/24 = -7/8

3) 2. 1/3 : (-2,8) = 2. 1/3 : (-2. 8/10) = 7/3 : (-28/10) = 7/3 * (-10/28) = 1/3 * (-10/4) = -10/12 = -5/6

4) -7/8 + (-5/6) = -7/8 - 5/6 = -21/24 - 20/24 = -41/24 =

-1. 17/24
