Haris Shaiful Bahari 20th January, 2009 Block C //__ Notes: __// *A ratio has 3 different ways in writing; (** X:X), (X/X) or (X to X). ** *The word percent means- per… cent/ per 100/ cent = century = 100/ out of 100 //__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. ** //__ Essential Question __//// : //// What methods are there for comparing things? //    A survey of 100 students at Neilson  Middle School found that 60 students prefer watching television in the evening and 40 students prefer listening to the radio. **//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 your answer.__** This report is accurate because they reduce 60 students to 6 and the total of 100 students to 10.  **// 2.) __Students prefer radio to television by a ratio of 4 to 6.__ //** This report is accurate because they reduced 40 students to 4 and 60 students to 6. **// 3. __Students who prefer television outnumber those who prefer radio by 20.__ //** This report is accurate because if you subtratct 40 students from 60 students you get 20 students. **// 4.)__Students who prefer television outnumber those who prefer radio by a ratio of 3 to 2.__ //** This report is accurate because when you reduce 60 and 40 to their lowest form 60 becomes 3 and 40 becomes 2. **//5.) __The number of students who prefer watching television is 1.5 times the number who prefer listening to radio.__//** This report is accurate because if you multiply 40 with 1.5 you will get 60. **// 6.) __40% of the students prefer radio to television.__ //** This report is true because there are already 100 students in total and 40 out of a 100 are 40%. This report is true because if you reduce 60 and 40 to their lowest form 60 would become 3 and 40 would become 3 and that means the total now is 5 so 3 students prefer watching television out of 5 student.  **//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 state from above would you use? Why?__** If I was trying to convince local merchants I would use advertisement number 6 because it only shows the data for radio but not television. **//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 use statement number 5 because it is only comparing Television to radio and it has only show data about television.   Conduct a quick survey in your class to find out how many people prefer watching television n the evening and how many prefer surfing the internet.    **Class Data Comparison Table**
