10 percent of what number is 30?

30 is 10% of 300

Working out percentages

  1. We have, 10% × x = 30
  2. or, 10/100 × x = 30
  3. Multiplying both sides by 100 and dividing both sides by 10,
    we have x = 30 × 100/10
  4. x = 300

    If you are using a calculator, simply enter 30×100÷10, which will give you the answer.
