Example 2: The following table shows the favourite activities of class V students:

Activities Watching TV Outdoor games Video games Reading
Number of students 24 36 24 12

Find the fraction for each activity. Draw a circle graph for the information given
in the table.
Solution: Step 1: First find the total number of students: 24 + 36 + 24 + 12 = 96
24 1 2
Fraction of students who like to watch TV = = =
96 4 8

Fraction of students who like to play outdoor games = 36 = 3

they are not, take an equivalent fraction. For example, for , take
into consideration. 4 8
Step 2: Draw a circle and divide it into 8 equal parts. Shade 2 parts for

watching TV, 3 parts for outdoor games, 2 parts for video games and
1 part for reading as shown in the given pie graph.
