- Who is the repeated identity? Give the answer in number. (Eg Bryan = 1, Charlie = 2, Adam = 3)
- Number of stickers that Adam has = _____ u
- Total number of stickers = _____ u
- Difference in the number of stickers between Bryan and Adam = _____ u
(a)
Change percentage into units.
Bryan has 30% more stickers than Charlie.
100% + 30% = 130%
130% =
130100 =
1310 Bryan has
1310 as many as Charlie.
Charlie has 50% more stickers than Adam.
100% + 50% = 150%
150% =
150100 =
32 Charlie has
32 as many as Adam.
Number of Charlie's stickers is compared to the number of Bryan's stickers.
Number of Charlie's stickers is compared to the number of Adam's stickers.
(2) Charlie is the repeated identity.

3x10 |
2x10 |
39 u |
30 u |
20 u |
(b)
LCM of 10 and 3 = 30
Number of stickers that Adam has = 20 u
(c)
Total number of stickers that the children have
= 39 u + 30 u + 20 u
= 89 u
(d)
Difference in the number of stickers between Bryan and Adam
= 39 u - 20 u
= 19 u
Answer(s): (a) 2; (b) 20; (c) 89; (d) 19
