Answer 2

To simplify the expression, let's break it down step by step:

1. Simplify the terms within the parentheses: -(-2 1/3 - 1 2/3) = 2 1/3 - 1 2/3 = 1 1/3 -(3 2/7 - 1 2/7) = 3 2/7 - 1 2/7 = 2 1/7

2. Now subtract the second result from the first result: 1 1/3 - 2 1/7

To perform the subtraction of mixed numbers, let's find a common denominator, which is the least common multiple (LCM) of 3 and 7, which is 21.

Converting both fractions to have a denominator of 21: 1 1/3 = 3/3 + 1/3 = 1 + 1/3 = 4/3 2 1/7 = 14/7 + 1/7 = 15/7

Now, subtracting: 4/3 - 15/7

To subtract fractions, they need to have a common denominator. The common denominator is already 21, so we can proceed: (4/3) * (7/7) - (15/7) * (3/3) (28/21) - (45/21)

Subtracting: (28 - 45) / 21 = -17/21

So, the result of the expression is -17/21, which can be further simplified if needed.
