How to convert decimals to fractions

So I will be explaining how to convert decimals to fractions and fractions to decimals. I will use 0.32 as an example. My teacher taught as to say the decimal out loud like zero and thirty two hundreths. Clearly it’s hundreths. The next step would be to simplify. You can simplify by finding the greatest common factor (GCF) to find the lowest thing it can be simplified to. However if the GCF is 1 then the number is simpified.
