Fill in the blanks.
Adam has 40% less stickers than Bryan and
Charlie has 30% less stickers than Adam.
- Who is the repeated identity? Give the answer in number. (Eg Charlie = 1; Bryan = 2; Adam = 3)
- Number of stickers that Bryan has = _____ u
- Total number of stickers = _____ u
- Difference in the number of stickers between Adam and Charlie = _____ u
(a)
Adam has 40% less stickers than Bryan.
100% - 40% = 60%
60% =
60100 =
35 Adam has
35 as many as stickers as Bryan.
Charlie has 30% less stickers than Adam.
100% - 30% = 70%
70% =
70100 =
710 Charlie has
710 as many as stickers as Adam.
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.
(3) Adam is the repeated identity.

3x10 |
5x10 |

10x3 |
|
7x3 |
30 u |
50 u |
21 u |
(b)
LCM of 3 and 10 = 30
Number of stickers that Bryan has = 50 u
(c)
Total number of stickers that the children have
= 30 u + 50 u + 21 u
= 101 u
(d)
Difference in the number of stickers between Adam and Charlie
= 30 u - 21 u
= 9 u
Answer(s): (a) 1; (b) 50; (c) 101; (d) 9
