I think you just use the math key. But finding percentage is really easy. All it is a decimal multiplied by 100. which means moving decimal point 2 to right.

Enter the fraction, as a division problem such as 2/3, then press math and choose >Percentage (or whatever it says...), then you get a decimal which is the percentage.
