2.5% of 750 vs 2.5% off 750
These two phrases sound similar but give different answers. 2.5% of 750 gives the percentage amount on its own: 18.75. 2.5% off 750 means subtracting that amount from 750, which leaves 731.25 (about 731.25 for money).
Worked side by side: "of" is just the product (2.5 ÷ 100) × 750 = 18.75. "Off" subtracts that product from the original: 750 − 18.75 = 731.25. Sales listings sometimes use either phrasing, so always check which one matches what you actually need.

Common mistakes to avoid
These are the four mistakes that most often turn a correct percentage problem into a wrong answer. Each one has a quick fix.
