Exercise 35 Page 142

Use the percent proportion.

What are we finding? A percent.
p≈1333 %

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 asked what percent? we will find a percent. We are given the values a= 400 and b= 30, and we will solve for the percent p.
a/b=p/100
SubstituteII

a= 400, b= 30

400/30=p/100
ReduceFrac

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

40/3=p/100
MultEqn

LHS * 100=RHS* 100

40/3*100=p
MoveRightFacToNum

a/c* b = a* b/c

4000/3=p
RearrangeEqn

Rearrange equation

p=4000/3

RoundInt

Round to nearest integer

p≈1333
The percent is approximately 1333 %.
