Fill in the blanks in whole numbers or fractions.
Some stickers are given to 4 children.
Christian has ⁵₇ of the stickers.
Adam has ⁴₅ of the remaining stickers.
Bryan has ¹₃ of the rest of the stickers.
David has the rest.
Let the number of stickers that Christian has be 5 u.

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

(a)
Change fraction into units.

Number of stickers that Christian has = 5 u

Fraction of the stickers given to Adam, David and Bryan
= 1 - ⁵₇
= ²₇

Number of remaining stickers = 2 u

Number of stickers that Adam has
= ⁴₅ x 2 u 
= ⁸₅ u
= 1³₅ u

(b)
Fraction of the remaining stickers given to Bryan and David
= 1 - ⁴₅
= ¹₅

Number of stickers that Bryan has
= ¹₅ x ¹₃ x 2 u 
= ²₁₅ u

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

Number of stickers that David has 
= ¹₅ x ²₃ x 2 u
= ⁴₁₅ u

Answer(s): (a) 1³₅; (b) ²₁₅; (c) ⁴₁₅
