Before |
8 x 8 = 64 u |
1 x 8 = 8 u |
9 x 8 = 72 u |

- 2 |
+ 2 |

After |
7 x 9 = 63 u |
1 x 9 = 9 u |
8 x 9 = 72 u |
(a)
Change X times into units.
There is an internal transfer of 2 stickers from Adam to Bryan.
The total remains unchanged.
LCM of 9 and 8 is 72.
Number of stickers that Adam gives to Bryan
= 64 u - 63 u
= 1 u
Difference in the number of stickers between Adam and Bryan at first
= 64 u - 8 u
= 56 u
(b)
Difference in the number of stickers between Adam and Bryan in the end
= 63 u - 9 u
= 54 u
(c)
Difference in the number of stickers that Adam has at first and in the end
= 64 u - 63 u
= 1 u
(d)
Difference in the number of stickers that Bryan has at first and in the end
= 9 u - 8 u
= 1 u
Answer(s): (a) 56; (b) 54; (c) 1; (d) 1
