Adam |
Bryan |
Comparing between Adam and Bryan at first |
5 x 9 = 45 u |
8 x 9 = 72 u |
Before |
9 x 5 = 45 u |
|
Change |
2 x 5 = - 10 u |
+ 10 u |
After |
7 x 5 = 35 u |
82 u |
(a)
Change ratio into units.
The amount that Adam has at first is repeated.
Amount that Adam has at first = 45 u
Amount that Bryan has at first = 72 u
Difference in the amount between Adam and Bryan at first
= 72 u - 45 u
= 27 u
(b)
Amount that Bryan has in the end
= 72 u + 10 u
= 82 u
(c)
Total amount that they have
= 45 u + 72 u
= 117 u
(d)
Difference in the amount that they have in the end
= 82 u - 35 u
= 47 u
47 u = 47
1 u = 47 ÷ 47 = 1
Answer(s): (a) 27; (b) 82; (c) 117; (d) 1
