Answer:
1. B. 3/7 (3 days : 7 days)
2. B. 1/6 [4 hours : 24 hours (4/24) = 1 hour : 6 hours (1/6)]
3. B. 1/4 [500 meters : 2000 meters (500/2000) = 1 meter : 4 meters (1/4)]
Step-by-step explanation:
If the solution is confusing, remember that I just simplified the resulting fractions. And also, 1 week = 7 days; 1 day = 24 hours; and 2 kilometers = 2000 meters.
I hope this helps.
