The problem in the image asks to find the total distance Alicia walked. Let's break it down.

Alicia walked:

1. $2 \frac{2}{5}$ km to college.
2. $1 \frac{1}{3}$ km to the mall.
3. $2 \frac{2}{5}$ km back home.

Step 1: Convert mixed fractions to improper fractions

1. $2 \frac{2}{5} = \frac{12}{5}$
2. $1 \frac{1}{3} = \frac{4}{3}$
3. $2 \frac{2}{5} = \frac{12}{5}$ (same as the first distance)

Step 2: Find the common denominator

To add these fractions, we need a common denominator. The least common denominator (LCD) of 5 and 3 is 15.

• $\frac{12}{5} = \frac{36}{15}$
• ( \frac{4}{
