Comparing between Adam and Bryan at first |
6 x 4 = 24 u |
7 x 4 = 28 u |
Before |
8 x 3 = 24 u |
|
Change |
5 x 3 = - 15 u |
+ 15 u |
After |

(a)
Change ratio into units.
The amount that Adam has at first is repeated.
Amount that Adam has at first = 24 u
Amount that Bryan has at first = 28 u
Difference in the amount between Adam and Bryan at first
= 28 u - 24 u
= 4 u
(b)
Amount that Bryan has in the end
= 28 u + 15 u
= 43 u
(c)
Total amount that they have
= 24 u + 28 u
= 52 u
(d)
Difference in the amount that they have in the end
= 43 u - 9 u
= 34 u
34 u = 34
1 u = 34 ÷ 34 = 1
Answer(s): (a) 4; (b) 43; (c) 52; (d) 1
