Fill in the blanks.
Adam has 20% more stickers than Bryan and 30% fewer stickers than Charlie.
- Who is the repeated identity? Give the answer in number. (Eg Bryan = 1; Adam = 2; Charlie = 3)
- Number of stickers that Bryan has = _____ u
- Total number of stickers = _____ u
- The difference in the number of stickers between Charlie and Adam = _____ u
(a)
Change percentage into units.
Adam has 20% more stickers than Bryan.
100% + 20% = 120%
120% =
120100 =
65 Adam has
65 as many as Bryan.
Adam has 30% fewer stickers than Charlie.
100% - 30% = 70%
70% =
70100 =
710 Adam has
710 as many as Charlie.
Number of Adam's stickers is compared to the number of Bryan's stickers.
Number of Adam's stickers is compared to the number of Charlie's stickers.
(2) 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 = 35 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 Charlie and Adam
= 60 u - 42 u
= 18 u
Answer(s): (a) 2; (b) 35; (c) 137; (d) 18
