Adam has 25% more stickers than Bryan.
- Who is the repeated identity? Give the answer in number. (Eg Charlie = 1, Adam = 2, Bryan = 3)
- Number of stickers that Bryan has = _____ u
- Total number of stickers = _____ u
- Difference in the number of stickers between Charlie and Bryan = _____ u
(a)
Change percentage into units.
Charlie has 30% more stickers than Adam.
100% + 30% = 130%
130% =
130100 =
1310 Charlie has
1310 as many as Adam.
Adam has 25% more stickers than Bryan.
100% + 25% = 125%
125% =
125100 =
54 Adam has
54 as many as Bryan.
Number of Adam's stickers is compared to the number of Charlie's stickers.
Number of Adam's stickers is compared to the number of Bryan's stickers.
(2) Adam is the repeated identity.

Bryan |
13x1 |
10x1 |

5x2 |
4x2 |
13 u |
10 u |
8 u |
(b)
LCM of 10 and 5 = 10
Number of stickers that Bryan 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 Charlie and Bryan
= 13 u - 8 u
= 5 u
Answer(s): (a) 2; (b) 8; (c) 31; (d) 5
