- What fraction of the pupils like rats?
- Given that 12 more pupils like chickens than rats, find the number of pupils in the class.
(a)
Fraction of the pupils that like chickens and terrapins
=
12 +
110=
510 +
110=
610=
35Fraction of the pupils that liked rats
= 1 -
35=
55 -
35=
25(b)
Difference between the fraction of the pupils that like chickens and fraction of the pupils that like rats
=
12 -
25=
510 -
410=
110Total number of pupils = 10 u
Number of pupils that like chickens more than rats = 1 u
1 u = 12
Total number of pupils
= 10 u
= 10 x 12
= 120
Answer(s): (a)
25; (b) 120
