Q.) calculate the proportion of energy with energy greater than activation every of 100kjmol-1 at 300kelvin

I used e-(ea/rt) hence got to 100,000÷(8.31x300) and then the answer to this is 40.11 then I did e^-(40.11) to get the fraction of molecules with energy but mark scheme has a different answer when I put in those figures. apparently it's 13 molecules in every 10^8 molecules... can't see why the hell it's that I keep getting 38 molecules for every 10^19
