5.
70% of n is 14.7
6. 113 is 13% of n
7. 28% of n is 196
8. 35% of n is 1200
9. 175.5 is 11% of n
10. nis 40% of 65
4.
Answers:
1. Base = n
Rate = 30%
Percentage = 1.8
n = 6
2. Base = 400
Rate = n%
Percentage = 240
n = 60%
3. Base = n
Rate = 30%
Percentage = 2.4
n = 8
4. Base = n
Rate = 25%
Percentage = 225
n = 900
5. Base = n
Rate = 70%
Percentage = 14.7
n = 21
6. Base = n
Rate = 13%
Percentage = 113
n = 869.23
7. Base = n
Rate = 28%
Percentage = 196
n = 700
8. Base = n
Rate = 35%
Percentage = 1200
n = 3,428.57
9. Base = n
Rate = 11%
Percentage = 175.5
n = 1,595.45
10. Base = 65
Rate = 40%
Percentage = n
n = 26
Formulas:
Base = Percentage / Rate
Rate = Percentage / Base
Percentage = Base x Rate
