You have the following information:
1. Jorge lives 5/6 miles from the playground. Then, when you divide 5 by 6, you obtain:
5/6 miles=0.83 miles
2. Lynne lives 4/6 mile from the playground. Then, you have:
4/6 miles=0.66 miles
3. Crosby lives 7/8 mile from the playground. So:
7/8 miles=0.87 miles
4. As you can see, Lynne lives 0.66 miles from the playground and Jorge 0.83 miles.
5. Therefore, the answer is: Lynne lives closer to the playground.
