Change ratio into units.
Number of girls = 9 u
Number of boys = 10 u
Difference between the number of boys and girls
= 10 u - 9 u
= 1 u
(b)
Total number of girls and boys
= 9 u + 10 u
= 19 u
(c)
Total number of stickers that the girls have
= 9 u x 8

Total number of stickers that the boys have
= 10 u x 11
= 110 u
Difference in the number of stickers that the girls and the boys have
= 110 u - 72 u
= 38 u
(d)
Total number of stickers that the girls and boys
= 72 u + 110 u
