7 x 7 = 49 u |
1 x 7 = 7 u |
8 x 7 = 56 u |

After |
6 x 8 = 48 u |
1 x 8 = 8 u |
7 x 8 = 56 u |
(a)
Change X times into units.
There is an internal transfer of 11 stickers from Bryan to Adam.
The total remains unchanged.
LCM of 8 and 7 is 56.
Number of stickers that Bryan gives to Adam
= 49 u - 48 u
= 1 u
Difference in the number of stickers between Bryan and Adam at first
= 49 u - 7 u
= 42 u
(b)
Difference in the number of stickers between Bryan and Adam in the end
= 48 u - 8 u
= 40 u
(c)
Difference in the number of stickers that Bryan has at first and in the end
= 49 u - 48 u
= 1 u
(d)
Difference in the number of stickers that Adam has at first and in the end
= 8 u - 7 u
= 1 u
Answer(s): (a) 42; (b) 40; (c) 1; (d) 1
