(a)
Change ratio into units.
Number of boys = 1 u
Number of girls = 10 u
Difference between the number of girls and boys
= 10 u - 1 u
= 9 u
(b)
Total number of boys and girls
= 1 u + 10 u
= 11 u
(c)
Total number of stickers that the boys have
= 1 u x 9
= 9 u
Total number of stickers that the girls have
= 10 u x 10
= 100 u
Difference in the number of stickers that the boys and the girls have
= 100 u - 9 u
= 91 u
(d)
Total number of stickers that the boys and girls
= 9 u + 100 u
= 109 u
