At a math convention, nine out of eleven people are bored by cable news. If there are 122 people at the convention who are not bored by cable news, then how many people at the convention are bored by cable news?
9/11 are bored.
122 aren't bored.
This means 122 = 2/11
122 ÷ 2 = 61
61 * 11 = 671, which is the number of people at the convention
671 * 9/11 = 549, which is your answer :)
Thanks so much!
