Fill in the blanks.
Charlie has 25% more stickers than Bryan and 25% fewer stickers than Adam.
- Who is the repeated identity? Give the answer in number. (Eg Charlie = 1; Bryan = 2; Adam = 3)
- Number of stickers that Adam has = _____ u
- Total number of stickers = _____ u
- The difference in the number of stickers between Adam and Bryan = _____ u
(a)
Change percentage into units.
Charlie has 25% more stickers than Bryan.
100% + 25% = 125%
125% =
125100 =
54 Charlie has
54 as many as Bryan.
Charlie has 25% fewer stickers than Adam.
100% - 25% = 75%
75% =
75100 =
34 Charlie has
34 as many as Adam.
Number of Charlie's stickers is compared to the number of Bryan's stickers.
Number of Charlie's stickers is compared to the number of Adam's stickers.
(1) Charlie is the repeated identity.

15 u |
12 u |
20 u |
(b)
Charlie is the repeated identity.
LCM of 5 and 3 = 15
Number of stickers that Adam has = 20 u
(c)
Total number of stickers that the children have
= 15 u + 12 u + 20 u
= 47 u
(d)
Difference in the number of stickers between Adam and Bryan
= 20 u - 12 u
= 8 u
Answer(s): (a) 1; (b) 20; (c) 47; (d) 8
