- Who is the repeated identity? Give the answer in number. (Eg Charlie = 1, Bryan = 2, Adam = 3)
- Number of stickers that Adam has = _____ u
- Total number of stickers = _____ u
- Difference in the number of stickers between Charlie and Adam = _____ u
(a)
Change percentage into units.
Charlie has 30% more stickers than Bryan.
100% + 30% = 130%
130% =
130100 =
1310 Charlie has
1310 as many as Bryan.
Bryan has 20% more stickers than Adam.
100% + 20% = 120%
120% =
120100 =
65 Bryan has
65 as many as Adam.
Number of Bryan's stickers is compared to the number of Charlie's stickers.
Number of Bryan's stickers is compared to the number of Adam's stickers.
(2) Bryan is the repeated identity.

6x5 |
5x5 |
39 u |
30 u |
25 u |
(b)
LCM of 10 and 6 = 30
Number of stickers that Adam has = 25 u
(c)
Total number of stickers that the children have
= 39 u + 30 u + 25 u
= 94 u
(d)
Difference in the number of stickers between Charlie and Adam
= 39 u - 25 u
= 14 u
Answer(s): (a) 2; (b) 25; (c) 94; (d) 14
