110=
610=
35Fraction of the pupils that liked guinea pigs

35=
55 -
35=
25(b)
Difference between the fraction of the pupils that like geckos and fraction of the pupils that like guinea pigs
=
12 -
25=
510 -
410=
110Total number of pupils = 10 u
Number of pupils that like geckos more than guinea pigs = 1 u
1 u = 9
Total number of pupils
= 10 u
= 10 x 9
= 90
Answer(s): (a)
