In the pupils,
12 of the pupils like spiders,
110 of the pupils like guinea pigs and the rest like tortoises
- What fraction of the pupils like tortoises?
- Given that 10 more pupils like spiders than tortoises, find the number of pupils in the class.
(a)
Fraction of the pupils that like spiders and guinea pigs
=
12 +
110=
510 +
110=
610=
35Fraction of the pupils that liked tortoises
= 1 -
35=
55 -
35=
25(b)
Difference between the fraction of the pupils that like spiders and fraction of the pupils that like tortoises
=
12 -
25=
510 -
410=
110Total number of pupils = 10 u
Number of pupils that like spiders more than tortoises = 1 u
1 u = 10
Total number of pupils
= 10 u
= 10 x 10
= 100
Answer(s): (a)
