- 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
- Difference in the number of stickers between Bryan and Charlie = _____ u
(a)
Change percentage into units.
Bryan has 30% more stickers than Adam.
100% + 30% = 130%
130% =
130100 =
1310 Bryan has
1310 as many as Adam.
Adam has 30% more stickers than Charlie.
100% + 30% = 130%
130% =
130100 =
1310 Adam has
1310 as many as Charlie.

|
13x10 |
10x10 |
169 u |
130 u |
100 u |
(b)
LCM of 10 and 13 = 130
Number of stickers that Charlie has = 100 u
(c)
Total number of stickers that the children have
= 169 u + 130 u + 100 u
= 399 u
(d)
Difference in the number of stickers between Bryan and Charlie
= 169 u - 100 u
= 69 u
Answer(s): (a) 2; (b) 100; (c) 399; (d) 69
