Exercise 34 Page 142

Use the percent proportion.

What are we finding? A part.
a=112

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. Since we are trying to find a percentage of a whole, we are finding a part. We are given the values p= 175 and b= 64, and we will solve for a.
a/b=p/100
SubstituteII

b= 64, p= 175

a/64=175/100
ReduceFrac

a/b=.a /25./.b /25.

a/64=7/4
MultEqn

LHS * 64=RHS* 64

a=7/4*64
MoveRightFacToNum

a/c* b = a* b/c

a=7*64/4
ReduceFrac

a/b=.a /4./.b /4.

a=7*16/1
DivByOne

a/1=a

a=7*16
Multiply

Multiply

a=112
The part is 112.
