Exercise 8 Page 140

To solve problems that involve percent, use the percent equation.

Equation: 16.1 = n* 70
Solution: n = 23 %

Practice makes perfect

Let's start by recalling that we can use the percent equation to solve problems that involve percent. Percent Equation [0.3em] part = percent * whole We want to find what percent of 70 is 16.1. Let n represent the percent. 16.1 = n * 70 Now we will solve the equation that we got for n. To do so, we will use the Division Property of Equality.

16.1=n* 70
16.1/70=70n/70
16.1/70=70n/70
16.1/70=n
0.23 =n
n = 0.23

We found that n= 0.23 is a solution to the equation. To write the decimal as a percent, we need to move the decimal point two places to the right and write the percent symbol. 0.23 = 23 % We got that 16.1 is 23 % of 70.
