- Number of stickers that Adam has = _____ u
- Total number of stickers = _____ u
- Difference in the number of stickers between Adam and Charlie = _____ u
(a)
Change percentage into units.
Bryan has 50% more stickers than Adam.

32 Bryan has
32 as many as Adam.
Adam has 25% more stickers than Charlie.
100% + 25% = 125%

15 u |
10 u |
8 u |
(b)
LCM of 2 and 5 = 10
Number of stickers that Adam has = 10 u
(c)
Total number of stickers that the children have
= 15 u + 10 u + 8 u
= 33 u
(d)
Difference in the number of stickers between Adam and Charlie
= 10 u - 8 u
= 2 u
Answer(s): (a) 2; (b) 10; (c) 33; (d) 2
