Is it allowed to use fractions instead of whole numbers when balancing equations, I assumed it was okay since I did that for combustion equations, however I just did a question now to balance an equation and I got this;
5Cl- + MnO4- + 8H+ --> 5/2Cl2 + Mn ^2 + 4H20
However the mark scheme times them all by two so that the fraction 5/2 because 5. The mark scheme made no mention of my equation so I'm assuming they only allowed their answer. However surely I'm right too? Or are fractions not allowed?

As long as there are an equal number of moles of each atom/species on each side, it doesn't matter if you use fractions or not.
