X% of Y = (X / 100) × Y
X is (X / Y × 100)% of Y
Change = (Y − X) / X × 100%
Pick the mode that matches your question. "X% of a number" finds a portion (e.g. a discount or tip); "X is what percent of Y" expresses one number as a percentage of another; "percentage change" gives the increase or decrease from a starting value to a new one (a positive result is an increase, a negative one a decrease).
