How to work it out

  1. Turn the percentage into a decimal: 400 ÷ 100 = 4
  2. Multiply: 4 × 70 = 280
  3. Check: Work backwards: 280 ÷ 70 × 100 = 400%.

Another method. As a proportion of part to whole: 400/100 = part/70, so part = 400 × 70 ÷ 100 = 280. Both methods always give the same answer.

In a spreadsheet: =400%*70. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.

What the result means

Because 400% is more than 100%, the answer is bigger than 70: it is 4 times 70.

Mark-ups: pricing an item at 400% of its $70 cost means selling it for $280.

Adding and taking away 400%

Increasing 70 by 400% gives 350. These do not cancel out: raising 70 by 400% and then lowering the result by 400% ends at -1,050, because the second 400% is taken of a bigger number.
