 * Big Idea-** **Many important practical and mathematical applications involve comparing quantities of one** **kind or another; it is important to know which method to use and how we should use them.**

1. 6 out of 10 students prefer television to radio. Yes, because 60 students prefer to watch television out of 100. It means 60:100 which is 6:10 = 6 out of 10 students. (Ratio)
 * A. Read the statements below about how Neilson students prefer to spend their evenings. Tell whether each statement accurately reports the results of the survey. Explain you answer.**

2. Students prefer radio to television by a ratio of 4 to 6. Yes, because 40 students prefer listening to the radio and 60 students prefer watching television, which is 40:60, simplify = 4 to 6. (Ratio)

3. Students who prefer television outnumber those who prefer radio by 20. Yes, because 60 - 40 = 20. (Difference)

4. Students who prefer television outnumber those who prefer radio by a ratio of 3 to 2. Yes, because when I simplify 60 to 40, the simplest ratio is 3 to 2. (Ratio)

5. The number of students who prefer watching television is 1.5 times the number who prefers listening to radio. Yes, because 1.5 times of 40 is 60. (scaling)

6. 40% of the students prefer radio to television. Yes, because 40/100 is 40% of 100 students. (Percent)

7. 3/5 of the students prefer radio to television. Yes, because 60/100 is equal to 3/5. (Fraction) I would choose number 5 because it says how much more people prefer television without comparing, so, this might be better to advertise.
 * B. If you were writing a paper to convince local merchants that they would reach more students by advertising on the radio than on television, which statement from above would you use? Why? **
 * C. Imagine that you are the advertising director for a television station in the town where Neilson is located. You have been asked to prepare a report for a meeting between your ad department and a large local skateboard manufacturer. Which accurate statement from above would you use to try to convince the manufacturer to advertise on your station? Why? **

I would choose number 3 because it shows the amount of people out of a hundred, who liked television more the radio. 1. 6 out of 7 students prefer Internet to television. 2. Student prefer TV to Internet by a ration of 2:12 3. Students who prefer Internet outnumber those who prefer TV by 10. 4. Students who prefer Internet outnumber those who prefer TV by a ration of 1:6 5. The number of students who prefer watching Internet is 6 times the number who prefers watching TV. 6. About 14% of students prefer TV to Internet. 7. 6/7 of the students prefer Internet to TV. Similar: I used ratio, fraction, decimal and percentage. Different: Numbers and Internet instead of radio
 * // __Follow- Up__ //**
 * 1. For each statement in part A on page 7, write a similar statement about your class data. **
 * 2. In what ways is your class data similar to the Neilson data? In what ways is your data different? **
 * 3. You may have heard people talk about atn interest group manipulation data to promote their cause. This doesn't mean they used incorrect data, but that they made careful decisions about which data to use and how to represent the data to support their cause. How could you manipulate you class data to persuade local merchants to advertise on radio rather than o television? **

Don't mention the Internet at all and compare television to radio. The number of students watching TV is 2 times bigger than students who listen to the radio. Have to put other things that people don’t like very much than TV and compare with that.
