Exercise 19 Page 135

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

Equation: 98 = n* 392
Solution: n = 25 %

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 392 is 98. Let n represent the percent. 98 = n * 392 Now we will solve the equation that we got for n. To do so, we will use the Division Property of Equality.

98=n* 392
98/392=392n/392
98/392=392n/392
98/392=n
0.25 =n
n = 0.25

We found that n= 0.25 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. 0.25 = 25 % We got that 98 is 25 % of 392.
