Question

-4.5 × 0.1 +(-3.7)×(-2.1)-(-5.4)×(-0.2)

Answer 1

-4,5 • 0,1 + (-3,7) • (-2,1) - (-5,4) • (-0,2) = -0,45 + 7,77 + 5,4 • (-0,2) = -0,45 + 7,77 - 1,08 = 6,24

Answer 2

-4.5 × 0.1 + (-3.7) × (-2.1) - (-5.4) × (-0.2)

First, we will perform the multiplications:

-4.5 × 0.1 = -0.45 (-3.7) × (-2.1) = 7.77 (-5.4) × (-0.2) = 1.08

Now we can substitute these values back into the original expression:

-0.45 + 7.77 - 1.08

Now we can add and subtract:

-0.45 + 7.77 = 7.32 7.32 - 1.08 = 6.24

So the final answer is 6.24.
