Answer 2

To perform the calculation, you can first simplify the expressions within the parentheses and then add the final result to 4 17/25.

Let's start with the subtraction inside the parentheses:

(9 12/25 - 8 16/25)

To subtract mixed numbers, first subtract the whole numbers and then subtract the fractions:

9 - 8 = 1 (whole numbers)

Now, subtract the fractions:

12/25 - 16/25 = (12 - 16)/25 = -4/25

So, the result of the subtraction inside the parentheses is 1 - 4/25.

Now, add this result to 4 17/25:

1 - 4/25 + 4 17/25

To add mixed numbers, first add the whole numbers:

1 + 4 = 5 (whole numbers)

Now, add the fractions:

-4/25 + 17/25 = (-4 + 17)/25 = 13/25

So, the final result is 5 13/25.
