Fill in the blanks in whole numbers or fractions.
Some stickers are given to 4 children.
Christian has ¹₈ of the stickers.
Bryan has ¹₅ of the remaining stickers.
Adam has ³₇ of the rest of the stickers.
David has the rest.
Let the number of stickers that Christian has be 1 u.

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

(a)
Change fraction into units.

Number of stickers that Christian has = 1 u

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

Number of remaining stickers = 7 u

Number of stickers that Bryan has
= ¹₅ x 7 u 
= ⁷₅ u
= 1²₅ u

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

Number of stickers that Adam has
= ⁴₅ x ³₇ x 7 u 
= 2²₅ u

(c)
Fraction of the rest of the stickers given to David
= 1 - ³₇
= ⁴₇

Number of stickers that David has 
= ⁴₅ x ⁴₇ x 7 u
= 3¹₅ u

Answer(s): (a) 1²₅; (b) 2²₅; (c) 3¹₅
