One half is larger. You can either use cross-multiplying or decimals to figure this out. One half in decimals is 0.5 while one third is only 0.3333333(3 continuing).
they aren't that different but the whole number needs to be converted for them to be the same
There is no difference in the procedure.
why do they move the decimals when multiplying
no.

Very.
You do the multiplication in exactly the same way. The only extra thing is that when multiplying decimals, you need to place the decimal point (or decimal comma - depending on your country) in the correct position. If one number has, for example, 3 digits after the decimal point, and the other 4, you need to place the decimal point in the result (BEFORE eliminating unnecessary zeros) in such a way that there are, in this example, 7 digits (3 + 4) to the right of the decimal point.
