Exercise 20 Page 141

Use the percent proportion.

0.01

Practice makes perfect

In the percent proportion, the ratio of the part a to the whole b is equal to the percent p written as a fraction. a/b=p/100 Given any two of these three variables, we can find the third one. In this exercise, we are given the values p= 1 and b= 1, and we are looking for the value of a.

a/b=p/100
SubstituteII

b= 1, p= 1

a/1=1/100
DivByOne

a/1=a

a=1/100
WriteDec

Write as a decimal

a=0.01

This means that 0.01 is 1 % of 1.
