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?

1/2
3 7/8
3
4

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

Asia walks 2 1/4 miles to the park.

Asia walks 1 6/8 miles to her friend's house.

To add these distances, we need to find a common denominator for 4 and 8. The common denominator is 8.

2 1/4 is equivalent to 8/4 + 1/4 = 9/4

1 6/8 is equivalent to 1 12/8 = 1 3/2 = 2 3/4

Now we can add the distances:

9/4 + 2 3/4 = 9/4 + 14/4 = 23/4

We can simplify 23/4 to 5 3/4.

So, Asia walks a total of 5 3/4 miles in all.

Therefore, the answer is 5 3/4.
