Exercise 2 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= 60 and b= 50, and we are looking for the percent p.

a/b=p/100

SubstituteII

a= 60, b= 50

60/50=p/100

ReduceFrac

a/b=.a /10./.b /10.

6/5=p/100

MultEqn

LHS * 100=RHS* 100

600/5=p

CalcQuot

Calculate quotient

120 = p

RearrangeEqn

Rearrange equation

p = 120

This means that 60 is 120 % of 50.
