Adam |
Comparing between Bryan and Adam at first |
5 x 8 = 40 u |
6 x 8 = 48 u |
Before |
8 x 5 = 40 u |
|
Change |
7 x 5 = - 35 u |
+ 35 u |
After |
1 x 5 = 5 u |
83 u |
(a)
Change ratio into units.
The amount that Bryan has at first is repeated.
Amount that Bryan has at first = 40 u
Amount that Adam has at first = 48 u
Difference in the amount between Bryan and Adam at first
= 48 u - 40 u
= 8 u
(b)
Amount that Adam has in the end
= 48 u + 35 u
= 83 u
(c)
Total amount that they have
= 40 u + 48 u
= 88 u
(d)
Difference in the amount that they have in the end
= 83 u - 5 u
= 78 u
78 u = 78
1 u = 78 ÷ 78 = 1
Answer(s): (a) 8; (b) 83; (c) 88; (d) 1
