(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 5 is 5.
Difference in the number of stickers between Bryan and Adam
= 10 u - 5 u
= 5 u
(b)
Number of stickers that Bryan and Adam had in the end
= 6 u + 1 u
= 7 u
(c)
Number of stickers that Bryan gives away
= 10 u - 6 u
= 4 u
(d)
4 u = 12
1 u = 12 ÷ 4 = 3
Answer(s): (a) 5 ; (b) 7; (c) 4 ; (d) 3
