Answer 2

To solve this expression, we'll follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

Let's break it down step by step:

1. Start with the innermost parentheses:

   7 3/4 - 23 = (31/4) - 23 = (31/4) - (92/4) = (31 - 92)/4 = -61/4

2. Now, we have:

   (5 + 3 5/8) - (-61/4)

3. Next, add the mixed number and the fraction:

   5 + 3 5/8 = 5 + 3 + 5/8 = 8 + 5/8

4. Now, we can subtract the two fractions:

   (8 + 5/8) - (-61/4)

5. Convert 8 to an equivalent fraction with a common denominator of 8:

   8 = 64/8

6. Now, we have:

   (64/8 + 5/8) - (-61/4)

7. Add the fractions:

   (69/8) - (-61/4)

8. To subtract a negative number, you can change it to addition:

   (69/8) + (61/4)

9. Find a common denominator, which is 8:

   (69/8) + (61/4) = (69/8) + (122/8)

10. Now, add the fractions:

(69/8) + (122/8) = (69 + 122)/8 = 191/8

So, the result of the expression is 191/8.
