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?

Let the total number of people at the Math convention==P

 

7 / 12 P - percentage of people bored by cable news

 

7/12P ==280

 

P==280 / (7/12) ==280 x 12/7 ==480 people at the Math convention.

 

480  -  280 ==200 people who are not bored by cable news.
