At a math convention, a poll is taken about cable news. It turns out that 7 out of every 12 people are bored by cable news. If there are 280 people at the convention who are bored by cable news, then how many people at the convention are not bored by cable news?
+131 We are told that 7 out of 12 people are bored by cable news and that 280 people at the convention are bored by cable news. We divide 280 by 7 and get 40. We multiply 40 by 12 to figure out the total number of people in the convention. This is 480(40x12) and we subtract that from the people who are bored by cable news(280). When we subtract 480-280 we get our final answer of 200 who are not bored by cable news.
Work:
7/12= 280/x
7x=3360
x=480
480-280=200
Final Answer: 200
