1. 100 % of 10 = 10
2. 12% of 72 = 8.64
3. 8% of 87.5 = 7
4. 6% of 200 = 12
5. 20% of 30 = 16
Remember the formula;
Percentage = Base x Rate
Base = Percentage / Rate
Rate = Percentage / Base
And in these kind of problems the Base (B) is always with the " of " word in the phrase, Percentage (P) is always with the " is " word while Rate (R) is always with " % " sign.
Example :
16 % of 300 is 48
Rate : 16%
Base : 300
Percentage : 48
