55 -
45=
15(b)
Difference between the fraction of the pupils that like pigs and fraction of the pupils that like tortoises

310 -
15=
310 -
210=
110Total number of pupils = 10 u
Number of pupils that like pigs more than tortoises = 1 u
1 u = 9
Total number of pupils
= 10 u
= 10 x 9
= 90
Answer(s): (a)
