[SOLVED] Casio fx-300MS plus
Does anyone know if this calculator casio fx-300MS plus, can invert fractions? eg if 5/4=1.25, is there an inverse function to give me the answer of 0.8? Anyone???:)

I don't know the calculator specficially but look for a $x^{-1}$ key. That's how it is listed on the keys for all the calculators I've seen.

If it's there then what you want to do is type in:
0.8 $x^{-1}$
