How do you find out the percentage of something?

Easy, lets say the price is $25.99, if you move the dot one space to the left, you will have the 10% which is 2.599 or more simplified $2.59 i you move another space more the dot you will have the 1% or 0.25 if you want to know the %26 you multiply 0.25X26 and you will have the result.
