1. A researcher collected data from car shoppers about their favorite car color. He asked 250 people about their favorite vehicl
e color and the survey revealed the following: 32% said blue, 24% said white, 20% said red, 18% said black, and 4% said silver. (a) What percent preferred a color other than blue, white, red, black, or silver?
(b) How many more people said their favorite color is white compared to those who said black?
(7/15)/(3/5) easy (a/b)/(c/d)=(a/b)(d/c) invert and multiply (what it does is it cancels the bottom and makes it one) (7/15)/(3/5)=(7/15)(5/3)=35/45=7/9
