Percentages from Data
Date: 4/12/96 at 16:53:17 From: Wolf Subject: percentages Dear Dr. Math I am trying to figure out several things. I have totaled the number of men and women responding to 4 different newsgroups; an all-male group, an all-female group, and 2 mixed-sex groups. I have also totaled their use of swear words, by board and by sex. What I want to know is how to figure out who's swearing more, men or women, percentage-wise. I can't think of how to do the percentages. So I guess my questions for you are how to do the percentages for: who swears more, men or women? How do the swearing patterns change when moving from single-sex to mixed-sex boards? This is driving me nuts. *Please* help me if you can. Thank you very much, firstname.lastname@example.org

Then you make this ratio into a fraction. Say it's 1/6 You want to find an equivalent fraction with 100, instead of 6, in the denominator. So you ask: 1 = ? - - 6 100 Now let's name the unknown x and rewrite that... 1 = x _ _ 6 100 Now we can solve this algebraically by multiplying both sides by 100: 1 x _ * 100 = _ * 100 6 100 100 ___ = x 6 Now let's reduce 100/6 to lowest terms to get 50/3. We can also rewrite 50/3 as 16 2/3. So 1/6 is the same as 16 2/3 percent. Does this make sense to you? Good luck with your project! -Doctor Jodi, The Math Forum
