The original prize: 14.649
New prize: 23.609
(the years here are not relevant, just to confuse you with more numbers)
the increase is 23.609-14.649=8.960
If we want to know the percentage, we need to know what percentage of the original prize is 8.960.
this is calculated like this:

ti make it into percentage, we multiply by 100%: 61.164%
The conversion factor should be multiplied in Step 2 instead of being divided.
