Adam |
Bryan |
Comparing between Adam and Bryan at first |
5 x 7 = 35 u |
8 x 7 = 56 u |
Before |
7 x 5 = 35 u |
|
Change |
2 x 5 = - 10 u |
+ 10 u |
After |
5 x 5 = 25 u |
66 u |
(a)
Change ratio into units.
The amount that Adam has at first is repeated.
Amount that Adam has at first = 35 u
Amount that Bryan has at first = 56 u
Difference in the amount between Adam and Bryan at first
= 56 u - 35 u
= 21 u
(b)
Amount that Bryan has in the end
= 56 u + 10 u
= 66 u
(c)
Total amount that they have
= 35 u + 56 u
= 91 u
(d)
Difference in the amount that they have in the end
= 66 u - 25 u
= 41 u
41 u = 82
1 u = 82 ÷ 41 = 2
Answer(s): (a) 21; (b) 66; (c) 91; (d) 2
