10 x 6 = 60 u |
1 x 6 = 6 u |
11 x 6 = 66 u |

After |
5 x 11 = 55 u |
1 x 11 = 11 u |
6 x 11 = 66 u |
(a)
Change X times into units.
There is an internal transfer of 75 stickers from Adam to Bryan.
The total remains unchanged.
LCM of 11 and 6 is 66.
Number of stickers that Adam gives to Bryan
= 60 u - 55 u
= 5 u
Difference in the number of stickers between Adam and Bryan at first
= 60 u - 6 u
= 54 u
(b)
Difference in the number of stickers between Adam and Bryan in the end
= 55 u - 11 u
= 44 u
(c)
Difference in the number of stickers that Adam has at first and in the end
= 60 u - 55 u
= 5 u
(d)
Difference in the number of stickers that Bryan has at first and in the end
= 11 u - 6 u
= 5 u
Answer(s): (a) 54; (b) 44; (c) 5; (d) 5
