1. I have at the moment a fx85GT PLUS calculator. but on many occasions the calculator gives me an answer in decimal. I tried pressing the ab/c- d/c button but it doesn't convert it to fractions. so like for example I need the answer in 3/4square root5 but the calculator gives it to me in decimals 0.3354101966. Is there any way I could convert the decimals to a fraction with or without the calculator. If it is without the calculator, please tell me if you have any quick methods. Thank you.

If you want a result in surds it's usually better not to use a calculator. Which exam is this for?

Calculators can only give an answer in fraction or surd when it's a direct answer. Press the shift bottom and then mode/setup and then press 1 and 2 subsequently. If your calculator still gives the answer in decimal it's because it's not a whole answer
