Ответ:13
2)-2,5×(-1,3)×4
3,25×4=13
Ответ:13
3)-0,25×(-0,3)×(-4)
0,75×(-4)=-3
Ответ:-3
4)-4×(-0,7)×5
-4×(-3,5)=14
Ответ:14
5)8/15×(-1/2)×(-3/4)
8/15×3/4=2/5
Ответ:2/5
6)(-3/4)×(-5)×4
-3/4×(-20)=15
Ответ:15

Answer 2

1. -0,2 * (-5) * 13 = 10.4

To solve this, simply multiply the three numbers together: -0.2 x -5 x 13 = 10.4

2. -2.5 * (-1.3) * 4 = 13

Again, just multiply the three numbers: -2.5 x -1.3 x 4 = 13

3. -0.25 * (-0.3) * (-4) = 0.3

Multiply the three numbers: -0.25 x -0.3 x -4 = 0.3

4. (-4) * (-0.7) * 5 = 14

Multiply the three numbers: -4 x -0.7 x 5 = 14

5. (8/15) * (-1)^2 * (-3/4) = 0.3

(-1)^2 is equal to 1, so this simplifies to: (8/15) * 1 * (-3/4) = -0.2.

6. (-3/4) * (-5) * 4 = 15

Multiply the three numbers: (-3/4) * (-5) * 4 = 15.
