Adam |
Comparing between Bryan and Adam at first |
4 x 3 = 12 u |
5 x 3 = 15 u |
Before |
6 x 2 = 12 u |
|
Change |
5 x 2 = - 10 u |
+ 10 u |
After |

25 u |
(a)
Change ratio into units.
The amount that Bryan has at first is repeated.
Amount that Bryan has at first = 12 u
Amount that Adam has at first = 15 u
Difference in the amount between Bryan and Adam at first
= 15 u - 12 u
= 3 u
(b)
Amount that Adam has in the end
= 15 u + 10 u
= 25 u
(c)
Total amount that they have
= 12 u + 15 u
= 27 u
(d)
Difference in the amount that they have in the end
= 25 u - 2 u
= 23 u
23 u = 23
1 u = 23 ÷ 23 = 1
Answer(s): (a) 3; (b) 25; (c) 27; (d) 1
