- Number of stickers that Charlie has = _____ u
- Total number of stickers = _____ u
- Difference in the number of stickers between Adam and Charlie = _____ u
(a)
Change percentage into units.
Adam has 30% more stickers than Bryan.
100% + 30% = 130%
130% =
130100 =
1310 Adam has
1310 as many as Bryan.
Bryan has 25% more stickers than Charlie.
100% + 25% = 125%
125% =
125100 =
54 Bryan has
54 as many as Charlie.
Number of Bryan's stickers is compared to the number of Adam's stickers.
Number of Bryan's stickers is compared to the number of Charlie's stickers.
(2) Bryan is the repeated identity.
Adam |
Bryan |
Charlie |
13x1 |
10x1 |
|

5x2 |
4x2 |
13 u |
10 u |
8 u |
(b)
LCM of 10 and 5 = 10
Number of stickers that Charlie has = 8 u
(c)
Total number of stickers that the children have
= 13 u + 10 u + 8 u
= 31 u
(d)
Difference in the number of stickers between Adam and Charlie
= 13 u - 8 u
= 5 u
Answer(s): (a) 2; (b) 8; (c) 31; (d) 5
