Hello,
Once you enter a fraction the calculator calculates it and displays a decimal result.So basically you cannot do fraction manipulations. However you can convert a decimal result into a fraction. To do the conversion, you enter the decimal number then you Press [MATH] and [1]. ( -->Frac) The number will be converted.
Similarly you can enter a fraction to a decimal number (-->Dec)
[MATH] [2:] [ENTER]. But I see no point in doing that, because any fraction entered is displayed as a decimal number.
Hope it helps
Addendum. There is a way to enter a fraction and have it reduced to its simplest form without converting it to a decimal number. Ex: 27/48 can be reduced further by dividing both elements by 3. To enter the fraction Press 27 [/] 48 [MATH][1:->Frac][ENTER] the screen displays 9/16.
So if you want to calculate with fractions and obtain results as fractions, insert the [MATH][1:->Frac]. Exemple 27/48 [x] 5/13
(27/48) [x] 5/13 [MATH][1:->Frac] [ENTER] gives 45/208.
