math question please help?
in an opinion poll 50 men and 40 women, 70% of the men and 25% of the women said they pereferred fiction to nofiction books. what percent of the number of people polled preferred to read fiction….? please help and show work
ok start with the women, 25% of 40 is 10 because you basically halve it and halve it again.
now the men 50% of 50 is 25, and 25% of 50 is 12.5. 25 Plus 12.5 is 37.5 and that is 75% 1% of 50 is 0.5. 0.5 times 5 is 2.5 so subtract 2.5 from 37.5 is 35.
10 plus 35 is 45 and that is out of 90 in total making the overall percentage of people who prefer to read fiction is 50% i think the other percentage is obviouse.
i worked it out by finding how many people read fiction so i sort of did it backwards
hope i got that all right, and i hope that helps

The Art of Fiction $12.99 In 1958, Ayn Rand, already the world-famous author of such bestselling books as atlas shrugged and The Fountainhead, gave a private series of extemporaneous lectures in her own living room on the art of fiction. Tore Boeckmann and Leonard Peikoff for the first time now bring readers the edited transcript of these exciting personal statements. The Art of Fiction offers invaluable lessons, in which Rand analyzes the four essential elements of fiction: theme, plot, characterization, and style. She demonstrates her ideas by dissecting her best-known works, as well as those of other famous authors, such as Thomas Wolfe, Sinclair Lewis, and Victor Hugo. An historic accomplishment, this compendium will be a unique and fascinating resource for both writers and readers of fiction. |
