In the students,
512 of the students like guinea pigs,
14 of the students like tortoises and the rest like hedgehogs
- What fraction of the students like hedgehogs?
- Given that 3 more students like guinea pigs than hedgehogs, find the number of students in the class.
(a)
Fraction of the students that like guinea pigs and tortoises
=
512 +
14=
512 +
312=
812=
23Fraction of the students that liked hedgehogs
= 1 -
23=
33 -
23=
13(b)
Difference between the fraction of the students that like guinea pigs and fraction of the students that like hedgehogs
=
512 -
13=
512 -
412=
112Total number of students = 12 u
Number of students that like guinea pigs more than hedgehogs = 1 u
1 u = 3
Total number of students
= 12 u
= 12 x 3
= 36
Answer(s): (a)
13; (b) 36
