A percentage is a ratio. You cannot obtain a ratio from an amount. You have something to compare it to. For instance, if you have 4 slices of Pizza out of a pie that had 8 slices you have 4/8 of the pizza. To convert it to a percentage you divide the numerator by the denominator (4 divided by 8) and then multiply by 100. This gives you 50, so you have 50% of the pizza.
