Hi guys.
I came across a lesson in my Algebra 2, and got completely lost. The lesson is about problems like this:
Astronomers found that 0.017 of the stars examined were red dwarfs. If 29,000 stars were examined, how many were not red dwarfs?
I tried to solve these problems like this:
(a) .017/1000 = red dwarfs/stars examined = n/29,000
(b) .017 times 29,000 divided by 1000 = n = .493
(c) 29,000 - .493 = Answer = 28999.507
However, the answer is close, but wrong, every time. This answer is 28,507 according to the answer key. Am I using the wrong formula to solve it? What am I doing wrong here?
Your help is greatly appreciated!
