Raymond needs to walk 3/4 mile to the bus stop .He has walked 3/8 mile so far. How much farther does Raymond need to walk to get to the bus stop?

Answer:
3/8 mile
Step-by-step explanation:
The number of miles farther Raymond needs to walk to get to the bus stop is calculated as:
Total number of miles he needs to walk to the bus stop - Number of miles he has walked so far
Total number of miles he needs to walk to the bus stop = 3/4 mile
Number of miles he has walked so far = 3/8 mile
Hence,
3/4 mile - 3/8 mile
Lowest Common Denominator = 8
2 × 3 - 3 × 1/8
6 - 3/8
= 3/8 mile
Option c is correct
