Multiply: `-(3a b^2)/5\ ` by `((2a)/3-b)`

Explanation

To solve the multiplication of the expression \(-\frac{3ab^2}{5}\) by \(\left(\frac{2a}{3} - b\right)\), we will follow these steps:

### Step 1: Distribute the first term
We will distribute \(-\frac{3ab^2}{5}\) to both terms in the second expression \(\left(\frac{2a}{3} - b\right)\).

\[ -\frac{3ab^2}{5} \cdot \frac{2a}{3} - \frac{3ab^2}{5} \cdot b \]
