Answer:

$1\frac{1}{15}$

Step-by-step explanation:

Let's use a start by using common denominators. $9\frac{2}{5} = 9\frac{6}{15}$ and $8\frac{1}{3} = 8 \frac{5}{15}$

Now, replace the original equation with the common denominators. $9\frac{6}{15} - 8\frac{5}{15}$

Solve! $9\frac{6}{15} - 8\frac{5}{15} = 1\frac{1}{15}$
