Kylie gave 2 stickers to every girl and 9 stickers to every boy in her class. There were 5 more girls than boys in the class. She gave away a total of 65 stickers.
- How many children were there in the class?
- How many less stickers were given to the girls than the boys?
(a)
There were more girls than boys in class.
If we remove the 5 extra girls, the number of girls and boys will be the same.
Kylie would give away less stickers.
Number of less stickers that Kylie needed to give away if there was 5 less girls
= 5 x 2
= 10
Number of stickers she would need if there was 5 less girls
= 65 - 10
= 55
Number of stickers to give for every 1 girl and 1 boy
= 2 + 9
= 11
Number of sets of 1 girl and 1 boy
= 55 ÷ 11
= 5
Number of boys = 5
Number of girls
= 5 + 5
= 10
Number of children
= 5 + 10
= 15
(b)
Number of stickers given to the girls
= 10 x 2
= 20
Number of stickers given to the boys
= 5 x 9
= 45
Number of less stickers given to the girls than the boys
= 45 - 20
= 25
Answer(s): (a) 15; (b) 25
