Answer 2

Let's simplify the expression step by step:

1/3 - (+2/3) - 2/5 - (-3/5)

First, let's simplify the addition and subtraction of fractions:

1/3 - 2/3 - 2/5 + 3/5

Now, find a common denominator for the fractions, which is the least common multiple (LCM) of 3 and 5, which is 15.

(1/3)(5/5) - (2/3)(5/5) - (2/5)(3/3) + (3/5)(3/3)

5/15 - 10/15 - 6/15 + 9/15

Now, add and subtract the fractions:

(5 - 10 - 6 + 9)/15

-2/15

So, the simplified value of the expression is -2/15.
