Change percentage into units.
Fill in the blanks.

Bryan has 50% less stickers than Adam and
Charlie has 25% less stickers than Bryan.

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

(a)
Bryan has 50% less stickers than Adam.

100% - 50% = 50%
50% = ⁵⁰₁₀₀ = ¹₂
Bryan has ¹₂ as many as stickers as Adam.

Charlie has 25% less stickers than Bryan.

100% - 25% = 75%
75% = ⁷⁵₁₀₀ = ³₄

Charlie has ³₄ as many as stickers as Bryan.

Number of Bryan's stickers is compared to the number of Adam's stickers.
Number of Bryan's stickers is compared to the number of Charlie's stickers.

(3) Bryan is the repeated identity.

Bryan	Adam	Charlie
1x4	2x4
4x1		3x1
4 u	8 u	3 u

(b)
LCM of 1 and 4 = 4

Number of stickers that Adam has = 8 u

(c)
Total number of stickers that the children have
= 4 u + 8 u + 3 u
= 15 u

(d)
Difference in the number of stickers between Bryan and Charlie
= 4 u - 3 u
= 1 u

Answer(s): (a) 1; (b) 8; (c) 15; (d) 1
