(a)
Fraction of the students that like dogs and lizards
=
512 +

312=
812=
23Fraction of the students that liked rats
= 1 -
23=
33 -
23=
13(b)
Difference between the fraction of the students that like dogs and fraction of the students that like rats
=
512 -
13=
512 -
412=
112Total number of students = 12 u
Number of students that like dogs more than rats = 1 u
1 u = 6
Total number of students
= 12 u
= 12 x 6
= 72
Answer(s): (a)
