(a)
The difference in the number of stickers that Adam and Bryan have at first and in the end is the same.
LCM of 1 and 3 is 3.
Difference in the number of stickers between Adam and Bryan
= 4 u - 1 u
= 3 u
(b)
Number of stickers that Adam and Bryan had in the end
= 6 u + 3 u
= 9 u
(c)
Number of stickers that Adam receives
= 6 u - 4 u
= 2 u
(d)
2 u = 20
1 u = 20 ÷ 2 = 10
Answer(s): (a) 3 ; (b) 9; (c) 2 ; (d) 10
