It is just a matter of being in EXACT mode. To set your calculator in EXACT mode here's the key sequence. Press [MODE] [F3] [Up Arrow] [Up Arrow] [Right Arrow] [2] [ENTER]. Now when your in the Matrix Editor you can input your numbers in decimal form and, they will be automatically be converted to a fractional format. Pictured below is a matrix that was entered using decimal numbers and, was converted into factional form. Notice at the bottom of the screen the calculator is in EXACT mode.
Here's the same matrix in the HOME screen.
Next is the same matrix converted back to decimal numbers. Notice at the bottom of the screen the calculator is in APPROX mode.
And of course when I turn the calculator back to EXACT mode and, Re-ENTER the decimal formatted matrix in the HOME screen the fractional formatted matrix reappearhow do i convert a - oneplusgh_8.jpg
You can use the propFrac( command but, having in the EXACT mode setting works better.
