Answer 2

1) -11,6+5,2=-6,4

2) -1 7/8= -15/8

3) -6,4*(-15/8)= -32/5*(-15/8)=32*15/5*8= 12

Answer 3

To calculate the expression (-11.6 + 5.2) * (-1 7/8), follow these steps:

Step 1: Simplify the expression inside the parentheses. (-11.6 + 5.2) = -6.4

Step 2: Convert the mixed number -1 7/8 to an improper fraction. To convert -1 7/8 to an improper fraction, we multiply the whole number (-1) by the denominator (8) and then add the numerator (7). The result becomes the new numerator, and the denominator remains the same. (-1 * 8) + 7 = -8 + 7 = -1 So, -1 7/8 can be written as -15/8.

Step 3: Multiply the simplified expression with the improper fraction. -6.4 * (-15/8)

To multiply fractions, you simply multiply the numerators together and the denominators together: (-6.4) * (-15/8) = (6.4) * (15/8)

Step 4: Calculate the product: (6.4) * (15/8) = 96/8 = 12

So, the result of the expression (-11.6 + 5.2) * (-1 7/8) is 12.
