It is a calculator and prqactically every button is a MATH button. It
depends on what MATH you intend to do. Put the calculator in Run/Mat
screen then press the OPTN key. You will see several tabs. Press the

You can convert a decimal number to a fraction using the >Frac command in the MATH menu. For example, to convert 0.2 to a fraction, press . 2 MATH 1 ENTER.
