Fill in the blanks.
Adam has 20% more stickers than Charlie and 30% fewer stickers than Bryan.
- Who is the repeated identity? Give the answer in number. (Eg Adam = 1; Charlie = 2; Bryan = 3)
- Number of stickers that Bryan has = _____ u
- Total number of stickers = _____ u
- The difference in the number of stickers between Bryan and Charlie = _____ u
(a)
Change percentage into units.
Adam has 20% more stickers than Charlie.
100% + 20% = 120%
120% =
120100 =
65 Adam has
65 as many as Charlie.
Adam has 30% fewer stickers than Bryan.
100% - 30% = 70%
70% =
70100 =
710 Adam has
710 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.
(1) Adam is the repeated identity.

10x6 |
42 u |
35 u |
60 u |
(b)
Adam is the repeated identity.
LCM of 6 and 7 = 42
Number of stickers that Bryan has = 60 u
(c)
Total number of stickers that the children have
= 42 u + 35 u + 60 u
= 137 u
(d)
Difference in the number of stickers between Bryan and Charlie
= 60 u - 35 u
= 25 u
Answer(s): (a) 1; (b) 60; (c) 137; (d) 25
