In the students,
310 of the students like pigs,
12 of the students like cats and the rest like rats
- What fraction of the students like rats?
- Given that 9 more students like pigs than rats, find the number of students in the class.
(a)
Fraction of the students that like pigs and cats
=
310 +
12=
310 +
510=
810=
45Fraction of the students that liked rats
= 1 -
45=
55 -
45=
15(b)
Difference between the fraction of the students that like pigs and fraction of the students that like rats
=
310 -
15=
310 -
210=
110Total number of students = 10 u
Number of students that like pigs more than rats = 1 u
1 u = 9
Total number of students
= 10 u
= 10 x 9
= 90
Answer(s): (a)
15; (b) 90
