(a)
Change X times into units.
There is an internal transfer of 144 stickers from Bryan to Adam.
The total remains unchanged.
LCM of 11 and 3 is 33.
Number of stickers that Bryan gives to Adam
= 30 u - 22 u
= 8 u
Difference in the number of stickers between Bryan and Adam at first
= 30 u - 3 u
= 27 u
(b)
Difference in the number of stickers between Bryan and Adam in the end
= 22 u - 11 u
= 11 u
(c)
Difference in the number of stickers that Bryan has at first and in the end
= 30 u - 22 u
= 8 u
(d)
Difference in the number of stickers that Adam has at first and in the end
= 11 u - 3 u
= 8 u
Answer(s): (a) 27; (b) 11; (c) 8; (d) 8
