Question

(-1,75)×(-2/7)²-(-11,55)÷3,3

Answer 1

( - 7/4 ) * ( 4/49 ) - ( - 3,5 ) = ( - 1/7 ) + ( 7/2) = ( - 1/7 ) + ( 7/2 ) = ( - 2/14 ) + ( 49/14 ) = 47/14

Answer 2

To calculate the expression (-1.75) × (-2/7)² - (-11.55) ÷ 3.3, follow these steps:

1. First, calculate (-2/7)²: (-2/7)² = (-2/7) × (-2/7) = 4/49

2. Now, calculate (-1.75) × (4/49): (-1.75) × (4/49) = -7/4 × 4/49 = -7/49

3. Next, calculate (-11.55) ÷ 3.3: (-11.55) ÷ 3.3 ≈ -3.5

4. Finally, subtract the result from step 3 from the result in step 2: -7/49 - 3.5 = (-7/49) - (171/49) = (-7 - 171)/49 = -178/49

So, the final result is -178/49.
