3)-0,25×(-0,3)×-4=-(0,25×0,3×4)=-(1×0,3)=-0.3

Answer 2

Let's calculate the given expressions step by step:

2. -2.5 × (-1.3) × 4

First, multiply the two negative numbers:

-2.5 × (-1.3) = 3.25

Now, multiply the result by 4:

3.25 × 4 = 13

So, the answer to the expression is 13.

3. -0.25 × (-0.3) × (-4)

First, multiply the two negative numbers:

-0.25 × (-0.3) = 0.075

Now, multiply the result by -4:

0.075 × (-4) = -0.3

So, the answer to the expression is -0.3.
