Solve the following problem: Asia walks 2 1/4 miles to the park and then another 1 6/8 miles to her friend’s house. How many miles does she walk in all?

To find the total distance that Asia walks, we need to add the distances she walks to the park and her friend's house.

The distance to the park is 2 1/4 miles.
The distance to her friend's house is 1 6/8 miles.

To add these distances, we first need to convert the fractions to have a common denominator.

The distance to the park can be written as 2 2/8 miles (since 1/4 is equivalent to 2/8).
The distance to her friend's house can be written as 1 3/8 miles (since 6/8 is equivalent to 3/8).

Now, we add the distances:

2 2/8 miles + 1 3/8 miles = 3 5/8 miles

Therefore, Asia walks a total of 3 5/8 miles.
