Change percentage into units.
Fill in the blanks.

Adam has 40% less stickers than Charlie and
Bryan has 50% less stickers than Adam.

1. Who is the repeated identity? Give the answer in number.  (Eg Bryan = 1; Charlie = 2; Adam = 3)
2. Number of stickers that Charlie has = _____ u
3. Total number of stickers = _____ u
4. Difference in the number of stickers between Adam and Bryan = _____ u

(a)
Adam has 40% less stickers than Charlie.

100% - 40% = 60%
60% = ⁶⁰₁₀₀ = ³₅
Adam has ³₅ as many as stickers as Charlie.

Bryan has 50% less stickers than Adam.

100% - 50% = 50%
50% = ⁵⁰₁₀₀ = ¹₂

Bryan has ¹₂ as many as stickers as Adam.

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.

(3) Adam is the repeated identity.

Adam	Charlie	Bryan
3x2	5x2
2x3		1x3
6 u	10 u	3 u

(b)
LCM of 3 and 2 = 6

Number of stickers that Charlie has = 10 u

(c)
Total number of stickers that the children have
= 6 u + 10 u + 3 u
= 19 u

(d)
Difference in the number of stickers between Adam and Bryan
= 6 u - 3 u
= 3 u

Answer(s): (a) 1; (b) 10; (c) 19; (d) 3
