Spending |
Savings |
Before |
2 x 3 = 6 u |
5 x 1 = 5 u |
If change |
+ 1 x 3 = + 3 u |
- 3 x 1 = - 3 u |
After |
3 x 3 = 9 u |
2 x 1 = 2 u |
(a)
Change percentage into units.
50% of spending = 60% of savings
12 of spending =
35 of savings
Make the numerators the same.
LCM of 1 and 3 = 3
1 x 32 x 3 of spending =
3 x 15 x 1 of savings
36 of spending =
35 of savings
Amount of spending = 6 u
(b)
Amount of savings = 5 u
(c)
Total amount of allowance
= 6 u + 5 u
= 11 u
(d)
Difference in the amount of spending and savings
= 6 u - 5 u
= 1 u
Answer(s): (a) 6; (b) 5; (c) 11; (d) 1
