Before |
8 x 5 = 40 u |
1 x 5 = 5 u |
9 x 5 = 45 u |
Change |
- 28 |
+ 28 |

After |
4 x 9 = 36 u |
1 x 9 = 9 u |
5 x 9 = 45 u |
(a)
Change X times into units.
There is an internal transfer of 28 stickers from Adam to Bryan.
The total remains unchanged.
LCM of 9 and 5 is 45.
Number of stickers that Adam gives to Bryan
= 40 u - 36 u
= 4 u
Difference in the number of stickers between Adam and Bryan at first
= 40 u - 5 u
= 35 u
(b)
Difference in the number of stickers between Adam and Bryan in the end
= 36 u - 9 u
= 27 u
(c)
Difference in the number of stickers that Adam has at first and in the end
= 40 u - 36 u
= 4 u
(d)
Difference in the number of stickers that Bryan has at first and in the end
= 9 u - 5 u
= 4 u
Answer(s): (a) 35; (b) 27; (c) 4; (d) 4
