Three ways to calculate percentages
X% of Y — find a portion of a number, e.g. "what is 20% of 500?"
X is what % of Y — express one number as a percentage of another, e.g. "150 is what percent of 500?"
% change from X to Y — find the percentage increase or decrease between two values, e.g. price before vs. after a discount.
