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

Charlie |
Bryan |
6x13 |
5x13 |
|
|
13x5 |
10x5 |
78 u |
65 u |
50 u |
(b)
LCM of 5 and 13 = 65
Number of stickers that Bryan has = 50 u
(c)
Total number of stickers that the children have
= 78 u + 65 u + 50 u
= 193 u
(d)
Difference in the number of stickers between Adam and Bryan
= 78 u - 50 u
= 28 u
Answer(s): (a) 2; (b) 50; (c) 193; (d) 28
