Answer 3

To solve this expression, you should 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. First, evaluate the expressions inside parentheses: 3/4 - 3/5 = (15/20) - (12/20) = (15 - 12) / 20 = 3/20

2. Now, we have the expression as follows: 9/10 - (3/20) + 5/8

3. Next, subtract 3/20 from 9/10: 9/10 - 3/20 = (18/20) - (3/20) = 15/20 = 3/4

4. Finally, add 3/4 to 5/8: 3/4 + 5/8 = (6/8) + (5/8) = 11/8

So, the simplified result of the expression is 11/8.
