Before |
4 x 4 = 16 u |
1 x 4 = 4 u |
5 x 4 = 20 u |
Change |
- 14 |
+ 14 |

After |
3 x 5 = 15 u |
1 x 5 = 5 u |
4 x 5 = 20 u |
(a)
Change X times into units.
There is an internal transfer of 14 stickers from Adam to Bryan.
The total remains unchanged.
LCM of 5 and 4 is 20.
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 - 4 u
= 12 u
(b)
Difference in the number of stickers between Adam and Bryan in the end
= 15 u - 5 u
= 10 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
= 5 u - 4 u
= 1 u
Answer(s): (a) 12; (b) 10; (c) 1; (d) 1
