Explanation:
To find the total distance walked, we need to add the distances walked to the music store and the grocery store.
Distance walked to the music store = 1/3 miles
Distance walked to the grocery store = 1/4 miles
Total distance walked = 1/3 + 1/4
We need to find a common denominator for 1/3 and 1/4. The least common multiple of 3 and 4 is 12. So, we can convert the fractions as follows:
1/3 = 4/12
1/4 = 3/12
Now, we can add the fractions:
4/12 + 3/12 = 7/12
Therefore, the total distance walked is 7/12 miles.
