In West Virginia, 100 days of the year (365)have temperatures less than32 degrees Fahrenheir. What (reduced) fraction of the days is that?
I'm not sure how to go about finding the answer. Can you please help?

well, just write
100/365
obviously 5 divides both top and bottom, so divide it out to get
20/73
Since 73 is prime, it has no factors in common with 20, so that's as far as you can go. 
100 out of 368 days =
100/365 = 20/73 
20.73
