Fill in the blanks in whole numbers or fractions.
Some stickers are given to 4 children.
Christian has ¹₈ of the stickers.
David has ¹₂ of the remaining stickers.
Bryan has ²₃ of the rest of the stickers.
Adam has the rest.
Let the number of stickers that Christian has be 1 u.

1. Number of stickers that David has = _____ u 
2. Number of stickers that Bryan has = _____ u 
3. Number of stickers that Adam has = _____ u 

(a)
Change fraction into units.

Number of stickers that Christian has = 1 u

Fraction of the stickers given to David, Adam and Bryan
= 1 - ¹₈
= ⁷₈

Number of remaining stickers = 7 u

Number of stickers that David has
= ¹₂ x 7 u 
= ⁷₂ u
= 3¹₂ u

(b)
Fraction of the remaining stickers given to Bryan and Adam
= 1 - ¹₂
= ¹₂

Number of stickers that Bryan has
= ¹₂ x ²₃ x 7 u 
= 2¹₃ u

(c)
Fraction of the rest of the stickers given to Adam
= 1 - ²₃
= ¹₃

Number of stickers that Adam has 
= ¹₂ x ¹₃ x 7 u
= 1¹₆ u

Answer(s): (a) 3¹₂; (b) 2¹₃; (c) 1¹₆
