Before |
8 x 2 = 16 u |
1 x 2 = 2 u |
9 x 2 = 18 u |

- 5 |
+ 5 |

After |
5 x 3 = 15 u |
1 x 3 = 3 u |
6 x 3 = 18 u |
(a)
Change X times into units.
There is an internal transfer of 5 stickers from Adam to Bryan.
The total remains unchanged.
LCM of 9 and 6 is 18.
Number of stickers that Adam gives to Bryan
= 16 u - 15 u
= 1 u
Difference in the number of stickers between Adam and Bryan at first
= 16 u - 2 u
= 14 u
(b)
Difference in the number of stickers between Adam and Bryan in the end
= 15 u - 3 u
= 12 u
(c)
Difference in the number of stickers that Adam has at first and in the end
= 16 u - 15 u
= 1 u
(d)
Difference in the number of stickers that Bryan has at first and in the end
= 3 u - 2 u
= 1 u
Answer(s): (a) 14; (b) 12; (c) 1; (d) 1
