Answer 2

First, let's simplify the expression within the parentheses:

2 3/5 - 3 1/2

To subtract these mixed numbers, we need to convert them to improper fractions:

2 3/5 = (2 x 5 + 3) / 5 = 13/5

3 1/2 = (3 x 2 + 1) / 2 = 7/2

So, now we can substitute and simplify the expression:

(13/5 - 7/2) * 2 2/9

To subtract these fractions, we need to find a common denominator. The smallest common multiple of 5 and 2 is 10, so we can rewrite the expression as:

(26/10 - 35/10) * 20/9

Simplifying the numerator:

(-9/10) * 20/9

The 9s cancel out, and we are left with:

-2

Therefore, the solution is -2.
