6 x 6 = 36 u |
1 x 6 = 6 u |
7 x 6 = 42 u |

After |
5 x 7 = 35 u |
1 x 7 = 7 u |
6 x 7 = 42 u |
(a)
Change X times into units.
There is an internal transfer of 14 stickers from Adam to Bryan.
The total remains unchanged.
LCM of 7 and 6 is 42.
Number of stickers that Adam gives to Bryan
= 36 u - 35 u
= 1 u
Difference in the number of stickers between Adam and Bryan at first
= 36 u - 6 u
= 30 u
(b)
Difference in the number of stickers between Adam and Bryan in the end
= 35 u - 7 u
= 28 u
(c)
Difference in the number of stickers that Adam has at first and in the end
= 36 u - 35 u
= 1 u
(d)
Difference in the number of stickers that Bryan has at first and in the end
= 7 u - 6 u
= 1 u
Answer(s): (a) 30; (b) 28; (c) 1; (d) 1
