(a)
Change X times into units.
The difference in the number of stickers that Bryan and Adam have at first and in the end is the same.
LCM of 1 and 4 is 4.
Difference in the number of stickers between Bryan and Adam
= 8 u - 4 u
= 4 u
(b)
Number of stickers that Bryan and Adam had in the end
= 5 u + 1 u
= 6 u
(c)
Number of stickers that Bryan gives away
= 8 u - 5 u
= 3 u
(d)
3 u = 18
1 u = 18 ÷ 3 = 6
Answer(s): (a) 4 ; (b) 6; (c) 3 ; (d) 6
