Bryan |
Comparing between Adam and Bryan at first |
5 x 7 = 35 u |
6 x 7 = 42 u |
Before |
7 x 5 = 35 u |
|
Change |
6 x 5 = - 30 u |
+ 30 u |
After |
1 x 5 = 5 u |
72 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 = 42 u
Difference in the amount between Adam and Bryan at first
= 42 u - 35 u
= 7 u
(b)
Amount that Bryan has in the end
= 42 u + 30 u
= 72 u
(c)
Total amount that they have
= 35 u + 42 u
= 77 u
(d)
Difference in the amount that they have in the end
= 72 u - 5 u
= 67 u
67 u = 67
1 u = 67 ÷ 67 = 1
Answer(s): (a) 7; (b) 72; (c) 77; (d) 1
