- 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 30% more stickers than Charlie.
100% + 30% = 130%
130% =
130100 =
1310 Adam has
1310 as many as Charlie.
Charlie has 40% more stickers than Bryan.
100% + 40% = 140%
140% =
140100 =
75 Charlie has
75 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.

Bryan |
13x7 |
10x7 |
|
|
7x10 |
5x10 |
91 u |
70 u |
50 u |
(b)
LCM of 10 and 7 = 70
Number of stickers that Bryan has = 50 u
(c)
Total number of stickers that the children have
= 91 u + 70 u + 50 u
= 211 u
(d)
Difference in the number of stickers between Adam and Bryan
= 91 u - 50 u
= 41 u
Answer(s): (a) 2; (b) 50; (c) 211; (d) 41
