(a)
The difference in the number of stickers that Bryan and Adam have at first and in the end is the same.
LCM of 2 and 3 is 6.
Difference in the number of stickers between Bryan and Adam
= 4 u - 1 u
= 6 u
(b)
Number of stickers that Bryan and Adam had in the end
= 18 u + 6 u
= 24 u
(c)
Number of stickers that Bryan receives
= 18 u - 4 u
= 14 u
(d)
14 u = 70
1 u = 70 ÷ 14 = 5
Answer(s): (a) 6 ; (b) 24; (c) 14 ; (d) 5
