Fill in the blanks.
Bryan has 20% more stickers than Adam and
Adam has 50% more stickers than Charlie.

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

(a)
Change percentage into units.

Bryan has 20% more stickers than Adam.

100% + 20% = 120%
120% = ¹²⁰₁₀₀ = ⁶₅

Bryan has ⁶₅ as many as Adam.

Adam has 50% more stickers than Charlie.

100% + 50% = 150%
150% = ¹⁵⁰₁₀₀ = ³₂

Adam has ³₂ 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.

(3) Adam is the repeated identity.

Bryan	Adam	Charlie
6x3	5x3
	3x5	2x5
18 u	15 u	10 u

(b)
LCM of 5 and 3 = 15

Number of stickers that Adam has = 15 u

(c)
Total number of stickers that the children have
= 18 u + 15 u + 10 u
= 43 u

(d)
Difference in the number of stickers between Adam and Charlie
= 15 u - 10 u
= 5 u

Answer(s): (a) 2; (b) 15; (c) 43; (d) 5
