Exercise 9 Page 133

Practice makes perfect
We want to find about what percent of viewers watch comedy, jokes, and bloopers. Let's use the percent equation. part = percent * whole According to the given diagram, 52.54 million out of about 142 million people watch comedy, jokes, and bloopers. Let n represent the desired percent. 52.54million = n * 142million Now we will solve the equation for n using the Division Property of Equality.

52.54million=n* 142million
52.54million/142million=n* 142million/142million
52.54 million/142 million=n* 142 million/142 million
52.54/142=n
0.37 =n
n=0.37

We got that n= 0.37 is the solution to the equation. To write a decimal as a percent, we need to move the decimal point two places to the right and write the percent symbol. 0.37 = 37 % Therefore, about 37 % of viewers watch comedy, jokes, and bloopers.

We are asked to find about what percent of viewers watch news stories. Let's use the percent equation again. part = percent * whole According to the given diagram, 44.02 million out of about 142 million people watch news stories. Let n represent the desired percent. 44.02million = n * 142million Now we will solve the equation for n using the Division Property of Equality.

44.02million=n* 142million
44.02million/142million=n* 142million/142million
44.02 million/142 million=n* 142 million/142 million
44.02/142=n
0.31 =n
n=0.31

We got that n= 0.31 is the 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. 0.31 = 31 % Therefore, about 31 % of viewers watch news stories.
