Before |
9 x 3 = 27 u |
1 x 3 = 3 u |
10 x 3 = 30 u |

- 26 |
+ 26 |

After |
5 x 5 = 25 u |
1 x 5 = 5 u |
6 x 5 = 30 u |
(a)
Change X times into units.
There is an internal transfer of 26 stickers from Adam to Bryan.
The total remains unchanged.
LCM of 10 and 6 is 30.
Number of stickers that Adam gives to Bryan
= 27 u - 25 u
= 2 u
Difference in the number of stickers between Adam and Bryan at first
= 27 u - 3 u
= 24 u
(b)
Difference in the number of stickers between Adam and Bryan in the end
= 25 u - 5 u
= 20 u
(c)
Difference in the number of stickers that Adam has at first and in the end
= 27 u - 25 u
= 2 u
(d)
Difference in the number of stickers that Bryan has at first and in the end
= 5 u - 3 u
= 2 u
Answer(s): (a) 24; (b) 20; (c) 2; (d) 2
