You can do it entirely in CAS, and it's guaranteed to be correct, unlike the Home method shown above which is NOT guaranteed to be correct, and in fact will ALWAYS be wrong if the fractions have more than a few digits in them, or if you're in FIX 2 mode or similar. Just type propfrac(Ans) and your fraction answer will be converted into the desired mixed number. The first example below is yours. The second example below shows how CAS gets the correct answer, but if you try the Home method it gets it wrong, even in Standard display mode. Only use the Home [a b/c] method if (1) you're in Standard display mode, and (2) the fraction only has a few digits in it (e.g. very simple homework problems!). <0ɸ0> Joe
