Just got a new TI-89 Titanium, can't really figure it out yet, I need help changing decimals to fractions, and fractions to decimals fast. Any ideas?

To convert a fraction to a decimal, type it out first, and before pressing Enter, press the diamond key to tell the TI to report the solution as a decimal. This works for all expressions that are expressed as fractions (exact answers).
To change the mode, go to Mode, Page 2, under Exact/Approx., change the value to Exact or Approximate, depending if you want decimals versus fractions all the time. I recommend leaving it on AUTO mode so that you get exact (fractional) answers by default unless you press the diamond key before entering the expression.

Or, if you want to make life easy, just type a period after a number in the fraction, and it will print out as a decimal.
For example, "4/3" is printed as "4/3", but "4/3." is printed as "1.33333"
