(a)
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 7 is 7.
Difference in the number of stickers between Bryan and Adam
= 8 u - 1 u
= 7 u
(b)
Number of stickers that Bryan and Adam had in the end
= 14 u + 7 u
= 21 u
(c)
Number of stickers that Bryan receives
= 14 u - 8 u
= 6 u
(d)
6 u = 30
1 u = 30 ÷ 6 = 5
Answer(s): (a) 7 ; (b) 21; (c) 6 ; (d) 5
