For some reason my TI89 Titanium is returning reduced fractions when I try to divide. I've spent an hour and a half combing every page of the manual and still cannot figure out how to get this calculator to DIVIDE two numbers instead of returning reduced fractions. For example I put in 100/16 and I get 25/4 instead of 6.25; I put in 5/7 and I get 5/7 instead of .7143. I'm having a really hard time believing that my 300 page manual doesn't cover this simple issue, but I've looked and looked and i just can't find it. Can anyone out there help me? Thanks.
