- Who is the repeated identity? Give the answer in number. (Eg Adam = 1; Bryan = 2; Charlie = 3)
- Number of stickers that Bryan has = _____ u
- Total number of stickers = _____ u
- Difference in the number of stickers between Charlie and Adam = _____ u
(a)
Charlie has 20% less stickers than Bryan.
100% - 20% = 80%
80% =
80100 =
45 Charlie has
45 as many as stickers as Bryan.
Adam has 50% less stickers than Charlie.

(b)
LCM of 4 and 2 = 4
Number of stickers that Bryan has = 5 u
(c)
Total number of stickers that the children have
= 4 u + 5 u + 2 u
= 11 u
(d)
Difference in the number of stickers between Charlie and Adam
= 4 u - 2 u
= 2 u
Answer(s): (a) 1; (b) 5; (c) 11; (d) 2
