Problem: Write the fraction representing the shaded portion.
The whole ball has been divided into 4 equal parts. Since only one of the four parts is shaded, the fraction representing the shaded portion would be ¼.
Problem: What fraction of an hour is 40 minutes?
1 hour = 60 min
1 min = 1/60 hours
40 min = 40/60 hours
