Simplify the expression: $\frac{1}{3}a^2b - \frac{3}{5}ab^2 + \frac{3}{8}a^2b^2 - \frac{5}{3}ab$

1. Problem Description

Simplify the expression:

$\frac{1}{3}a^2b - \frac{3}{5}ab^2 + \frac{3}{8}a^2b^2 - \frac{5}{3}ab$

2. Solution Steps

First, we identify like terms. There are no like terms in this expression. Therefore, we simply rewrite the expression.

$\frac{1}{3}a^2b - \frac{3}{5}ab^2 + \frac{3}{8}a^2b^2 - \frac{5}{3}ab$

Since there are no like terms, we cannot combine any of the terms.

3. Final Answer

$\frac{1}{3}a^2b - \frac{3}{5}ab^2 + \frac{3}{8}a^2b^2 - \frac{5}{3}ab$
