Exercise 14 Page 141

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 a= 88 and b= 88, and we are looking for the percent p.

a/b=p/100

SubstituteII

a= 88, b= 88

88/88=p/100

ReduceFrac

a/b=.a /88./.b /88.

1/1=p/100

MultEqn

LHS * 100=RHS* 100

100 = p

RearrangeEqn

Rearrange equation

p=100

This means that 88 is 100 % of 88.
