Answer:
B. 1 1/4+5 5/6=7 1/12
Step-by-step explanation:
Gretchen rode her snowmobile 1 1/4 miles to a snowmobile trail. She rode on the trail for 5 5/6 miles and then rode back home. Which addition sentence shows how many miles Gretchen rode in all?
This is calculated as:
1 1/4 miles + 5 5/6 miles
1 + 5 + ( 1/4 + 5/6)
Lowest common denominator = 12
6 + ( 3 + 10/12)
6 + 13/12
6 + 1 1/12
7 1/12
Option B is correct
