- What fraction of the pupils like pigs?
- Given that 7 more pupils like terrapins than pigs, find the number of pupils in the class.
(a)
Fraction of the pupils that like terrapins and snakes
=
512 +
14=
512 +
312=
812=
23Fraction of the pupils that liked pigs
= 1 -
23=
33 -
23=
13(b)
Difference between the fraction of the pupils that like terrapins and fraction of the pupils that like pigs
=
512 -
13=
512 -
412=
112Total number of pupils = 12 u
Number of pupils that like terrapins more than pigs = 1 u
1 u = 7
Total number of pupils
= 12 u
= 12 x 7
= 84
Answer(s): (a)
13; (b) 84
