Answer 3

To simplify the expression:

(-4/1 + 5/1) - (4.7 - 2.8) - 1.75

Step 1: Simplify the fractions in the first set of parentheses: (-4/1 + 5/1) = (-4 + 5) = 1

Now the expression becomes:

1 - (4.7 - 2.8) - 1.75

Step 2: Subtract the value inside the second set of parentheses: (4.7 - 2.8) = 1.9

Now the expression becomes:

1 - 1.9 - 1.75

Step 3: Subtract the remaining numbers:

1 - 1.9 = -0.9 -0.9 - 1.75 = -2.65

So, the simplified value of the expression is -2.65.
