Answer 3

To solve the expression (912/25 - 816/25) + 4*17/25, follow the order of operations (PEMDAS/BODMAS):

1. Multiply the numbers within parentheses: (9 * 12/25) - (8 * 16/25) + (4 * 17/25)

2. Perform the multiplications within each parentheses: (108/25) - (128/25) + (68/25)

3. Find the common denominator for all the fractions, which is 25: (108/25) - (128/25) + (68/25)

4. Subtract the fractions: (108 - 128 + 68) / 25

5. Simplify the numerator: (-20 + 68) / 25

6. Complete the subtraction: 48/25

Therefore, the expression (912/25 - 816/25) + 4*17/25 evaluates to 48/25.
