(a)
The difference in the number of stickers that Adam and Bryan have at first and in the end is the same.
LCM of 2 and 4 is 4.
Difference in the number of stickers between Adam and Bryan
= 5 u - 1 u
= 4 u
(b)
Number of stickers that Adam and Bryan had in the end
= 12 u + 4 u
= 16 u
(c)
Number of stickers that Adam receives
= 12 u - 5 u
= 7 u
(d)
7 u = 70
1 u = 70 ÷ 7 = 10
Answer(s): (a) 4 ; (b) 16; (c) 7 ; (d) 10
