Answer 2

Let's solve each of the given expressions step by step:

1. -0.2 - (-5) - 13:52

Step 1: Simplify the negative within the parentheses: -0.2 - (-5) = -0.2 + 5 = 4.8

Step 2: Now, we need to convert 13 hours and 52 minutes into decimal hours: 13 hours and 52 minutes = 13 + (52 / 60) hours ≈ 13.87 hours

Step 3: Combine the results: 4.8 - 13.87 ≈ -9.07

So, the result of the expression is approximately -9.07.

2. -2.5 - (-1,3 - 4)

Note: There seems to be a formatting issue with the expression. I'm assuming that the comma in "-1,3" is a typo and that you meant "-1.3". If that's not the case, please provide the correct expression.

Step 1: Simplify the negative within the parentheses: -1.3 - 4 = -5.3

Step 2: Combine the results: -2.5 - (-5.3) = -2.5 + 5.3 = 2.8

So, the result of the expression is 2.8.

3. -0.25 - (-0.3) - (-4)

Step 1: Simplify the negatives within the parentheses: -0.25 - (-0.3) = -0.25 + 0.3 = 0.05

Step 2: Simplify the negative outside the last parentheses: 0.05 - (-4) = 0.05 + 4 = 4.05

So, the result of the expression is 4.05.
