Fill in the blanks.
Adam has 40% more stickers than Charlie and 50% more stickers than Bryan.

1. Who is the repeated identity? Give the answer in number. (Eg Adam = 1; Charlie = 2; Bryan = 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.

Adam has 40% more stickers than Charlie.

100% + 40% = 140%
140% = ¹⁴⁰₁₀₀ = ⁷₅

Adam has ⁷₅ as many as Charlie.

Adam has 50% more stickers than Bryan.

100% + 50% = 150%
150% = ¹⁵⁰₁₀₀ = ³₂

Adam has ³₂ as many as Bryan.

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.

(1) Adam is the repeated identity.

Adam	Charlie	Bryan
7x3	5x3
3x7		2x7
21 u	6 u	35 u

(b)
LCM of 7 and 3 = 21

Number of stickers that Adam has = 21 u

(c)
Total number of stickers that the children have
= 21 u + 6 u + 35 u
= 62 u

(d)
Difference in the number of stickers between Adam and Charlie
= 21 u - 6 u
= 15 u

Answer(s): (a) 1; (b) 21; (c) 62; (d) 15
