In the students,
310 of the students like cats,

- What fraction of the students like guinea pigs?
- Given that 10 more students like cats than guinea pigs, find the number of students in the class.
(a)
Fraction of the students that like cats and rats
=
310 +
12=
310 +
510=
810=
45Fraction of the students that liked guinea pigs
= 1 -
45=
55 -
45=
15(b)
Difference between the fraction of the students that like cats and fraction of the students that like guinea pigs
=
310 -
15=
310 -
210=
110Total number of students = 10 u
Number of students that like cats more than guinea pigs = 1 u
1 u = 10
Total number of students
= 10 u
= 10 x 10
= 100
Answer(s): (a)
15; (b) 100
