Answer 2

To calculate the expression, you need to perform the subtraction and addition operations while also converting mixed numbers to improper fractions. Here's the step-by-step calculation:

1. Convert mixed numbers to improper fractions: -2 = -2/1 7/12 remains as it is -3 5/8 = -3 - 5/8 = -24/8 - 5/8 = -29/8 1 1/4 = 1 + 1/4 = 4/4 + 1/4 = 5/4

2. Now, perform the subtraction and addition: -2/1 + 7/12 + 29/8 - 5/4

3. Find a common denominator for the fractions: The common denominator for 1, 12, 8, and 4 is 24.

4. Convert all fractions to have the same denominator: -2/1 * 24/24 = -48/24 7/12 * 2/2 = 14/24 29/8 * 3/3 = 87/24 5/4 * 6/6 = 30/24

5. Now the expression becomes: (-48/24) + (14/24) + (87/24) - (30/24)

6. Combine the fractions: (-48 + 14 + 87 - 30) / 24 = 23/24

So, the result of the expression is 23/24.
