(a)
Fraction of the pupils that like guinea pigs and geckos
=
12 +
110=
510 +
110=
610=
35Fraction of the pupils that liked chickens
= 1 -
35=
55 -
35=
25(b)
Difference between the fraction of the pupils that like guinea pigs and fraction of the pupils that like chickens
=
12 -
25=
510 -
410=
110Total number of pupils = 10 u
Number of pupils that like guinea pigs more than chickens = 1 u
1 u = 4
Total number of pupils
= 10 u
= 10 x 4
= 40
Answer(s): (a)
