Fill in the blanks.
Bryan has 50% more stickers than Adam and 30% fewer stickers than Charlie.
- Who is the repeated identity? Give the answer in number. (Eg Bryan = 1; Adam = 2; Charlie = 3)
- Number of stickers that Charlie has = _____ u
- Total number of stickers = _____ u
- The difference in the number of stickers between Charlie and Adam = _____ u
(a)
Change percentage into units.
Bryan has 50% more stickers than Adam.
100% + 50% = 150%
150% =
150100 =
32 Bryan has
32 as many as Adam.
Bryan has 30% fewer stickers than Charlie.
100% - 30% = 70%
70% =
70100 =
710 Bryan has
710 as many as Charlie.
Number of Bryan's stickers is compared to the number of Adam's stickers.
Number of Bryan's stickers is compared to the number of Charlie's stickers.
(1) Bryan is the repeated identity.

21 u |
14 u |
30 u |
(b)
Bryan is the repeated identity.
LCM of 3 and 7 = 21
Number of stickers that Charlie has = 30 u
(c)
Total number of stickers that the children have
= 21 u + 14 u + 30 u
= 65 u
(d)
Difference in the number of stickers between Charlie and Adam
= 30 u - 14 u
= 16 u
Answer(s): (a) 1; (b) 30; (c) 65; (d) 16
