It took me a while to figure it out too but i found out how. Put in, for example, 3 divided by 2. You get 3/2. Then press the button right above DEL. (it says S<=>D) and it will convert the fraction to a decimal. To change the number of decimal places shown, push SHIFT then SETUP then 6 then a number from 1-9 and that is how many decimal places will be shown.
