Answer 3

To solve the expression, let's perform the operations step by step:

1. Convert all mixed numbers to improper fractions: -2 3/8 = -(2 + 3/8) = - (16/8 + 3/8) = -19/8 1 4/9 = 1 + 4/9 = (9 + 4)/9 = 13/9 3 5/8 = 3 + 5/8 = (24 + 5)/8 = 29/8

2. Now, rewrite the expression: -19/8 + 1/3 - 13/9 - 5/9 + 2/3 - 29/8

3. Find a common denominator for all fractions, which is 72 (8 * 9): -19/8 = -19/8 * 9/9 = -171/72 1/3 = 1/3 * 24/24 = 24/72 -13/9 = -13/9 * 8/8 = -104/72 -5/9 = -5/9 * 8/8 = -40/72 2/3 = 2/3 * 24/24 = 48/72 -29/8 = -29/8 * 9/9 = -261/72

4. Now the expression becomes: -171/72 + 24/72 - 104/72 - 40/72 + 48/72 - 261/72

5. Combine like terms: = (-171 + 24 - 104 - 40 + 48 - 261) / 72 = (-504) / 72 = -7

So, the result of the expression is -7.
