Finding the Percentage of the Given Number
Base - is the number from which a certain percent is to be
taken out. It is the quantity that represents the whole. It is the
number after the word “of”.
90% of 60 = 54
Encircle the Base
1.) 60% of 60 = 36
2.) 50 is n% of 650
3.) 95% of n = 19
4.) n% of 60 = 15
5.) 65% of 200 = n
6.) 30% of n = 600
How will you solve for the base?
Use the formula P
R
Example:
20% of n=20
R=20%
P=20
R=?
P = P/R
P = 20/20%
P = 20/.20
P= .1 X 100
P = 20
