Answer 2

To solve this problem, you can follow these steps:

1. Convert all the mixed fractions into improper fractions.
2. Perform the subtraction and addition operations as indicated.

Let's break down the problem step by step:

1. Convert the mixed fractions to improper fractions:

   • $8 \frac{2}{5}$ can be converted to $\frac{42}{5}$.
   • $6 \frac{4}{5}$ can be converted to $\frac{34}{5}$.
   • $3 \frac{3}{5}$ can be converted to $\frac{18}{5}$.
   • $4 \frac{2}{5}$ can be converted to $\frac{22}{5}$.

2. Now, perform the operations: $\frac{42}{5} + \frac{34}{5} - \frac{18}{5} - \frac{22}{5}$

   $\frac{42 + 34 - 18 - 22}{5}$

   $\frac{36}{5}$

So, $8 \frac{2}{5} + 6 \frac{4}{5} - 3 \frac{3}{5} - 4 \frac{2}{5} = \frac{36}{5}$ or $7 \frac{1}{5}$ as a mixed fraction.
