Answer 2

To solve this expression, you can start by subtracting the first two mixed numbers and then adding the third one:

(8 3/17 - 7 15/17) + 3 15/17

First, subtract the two mixed numbers inside the parentheses:

(8 3/17 - 7 15/17) = (8 - 7) + (3/17 - 15/17)

Now, subtract the whole numbers:

1 + (3/17 - 15/17)

Next, subtract the fractions:

1 + (-12/17)

Now, add the last mixed number:

1 + (-12/17) + 3 15/17

To add a mixed number to a fraction, you need to convert the mixed number to an improper fraction:

1 = 17/17 (because 1 whole is the same as 17/17)

Now, add the fractions:

(17/17) + (-12/17) + (51/17)

Combine the fractions:

(17 - 12 + 51)/17 = 56/17

Now, convert the improper fraction back to a mixed number:

56/17 = 3 5/17

So, the final result is:

1 + 3 5/17 = 4 5/17
