C. 3/10

of a mile

D. 2/5

of a mile

Answer 1

Answer: C. 3/10 of a mile

Explanation:

1. You know that:

- The distance between Mike’s house and the grocery store is 4/5 of a mile.

- He has walked 1/2 of a mile from his house to the grocery store.

2. Keeping this on mind, you can calculate the rest of the distance he need to walk (which you can call d) to reach the grocery store by subtracting 4/5 of a mile and 1/2 of a mile, as you can see below:

`d=(4)/(5)mile-(1)/(2)mile\\d=(3)/(10)mile`

3. The answer is the option C.
