- What fraction of the pupils like pigs?
- Given that 9 more pupils like snakes than pigs, find the number of pupils in the class.
(a)
Fraction of the pupils that like snakes and tortoises
=
310 +
12=
310 +
510=
810=
45Fraction of the pupils that liked pigs
= 1 -
45=
55 -
45=
15(b)
Difference between the fraction of the pupils that like snakes and fraction of the pupils that like pigs
=
310 -
15=
310 -
210=
110Total number of pupils = 10 u
Number of pupils that like snakes more than pigs = 1 u
1 u = 9
Total number of pupils
= 10 u
= 10 x 9
= 90
Answer(s): (a)
15; (b) 90
