Fill in the blanks.
Bryan has 40% more stickers than Adam and 25% fewer stickers than Charlie.
- Who is the repeated identity? Give the answer in number. (Eg Adam = 1; Bryan = 2; Charlie = 3)
- Number of stickers that Adam has = _____ u
- Total number of stickers = _____ u
- The difference in the number of stickers between Charlie and Bryan = _____ u
(a)
Change percentage into units.
Bryan has 40% more stickers than Adam.
100% + 40% = 140%
140% =
140100 =
75 Bryan has
75 as many as Adam.
Bryan has 25% fewer stickers than Charlie.
100% - 25% = 75%
75% =
75100 =
34 Bryan has
34 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.

21 u |
15 u |
28 u |
(b)
Bryan is the repeated identity.
LCM of 7 and 3 = 21
Number of stickers that Adam has = 15 u
(c)
Total number of stickers that the children have
= 21 u + 15 u + 28 u
= 64 u
(d)
Difference in the number of stickers between Charlie and Bryan
= 28 u - 21 u
= 7 u
Answer(s): (a) 2; (b) 15; (c) 64; (d) 7
