(a)
Total number of stickers received = 5 u
5 u = 90
1 u = 90 ÷ 5 = 18
Total number of stickers that Ethan, Ken and Luke received
= 90 - 18
= 72
Total number of stickers that Ethan, Ken and Luke received
= 1 p + 5 p
= 6 p
1 p = 72 ÷ 6 = 12
Number of stickers that Ethan received
= 1 p
= 12
(b)
Number of more stickers that Oliver received more than Ken
= 1 u - 1 p
= 18 - 12
= 6
Answer(s): (a) 12; (b) 6
