Question

2,7*(-2,03)-(-6,75):2,25-6,12:(3-3,25)

Answer 1

2,7*(-2,03)-(-6,75):2,25-6,12:(3-3,25) = 21,999

1) 2,7*(-2,03) = -5,481

2) (-6,75):2,25 = -3

3) -5,481-(-3) = -2,481

4) 3-3,25 = -0,25

5) 6,12:(-0,25) = -24,48

6) -2,481-(-24,48) = 21,999

Answer 2

To solve the expression, let's break it down step by step:

2,7*(-2,03) - (-6,75) : 2,25 - 6,12 : (3 - 3,25)

Step 1: Calculate the multiplication first: 2,7 * (-2,03) = -5.481

The expression now becomes: -5.481 - (-6,75) : 2,25 - 6,12 : (3 - 3,25)

Step 2: Calculate the subtraction of negative numbers: -5.481 - (-6,75) = -5.481 + 6,75 = 1.269

The expression now becomes: 1.269 : 2,25 - 6,12 : (3 - 3,25)

Step 3: Calculate the subtraction inside the parentheses: 3 - 3,25 = -0.25

The expression now becomes: 1.269 : 2,25 - 6,12 : (-0.25)

Step 4: Calculate the division: 1.269 : 2,25 = 0.564

The expression now becomes: 0.564 - 6,12 : (-0.25)

Step 5: Calculate the division: 6,12 : (-0.25) = -24.48

The expression now becomes: 0.564 - (-24.48)

Step 6: Calculate the subtraction of negative numbers: 0.564 - (-24.48) = 0.564 + 24.48 = 25.044

Therefore, the value of the expression 2,7*(-2,03)-(-6,75):2,25-6,12:(3-3,25) is approximately 25.044.
