How to work it out

  1. Turn the percentage into a decimal: 350 ÷ 100 = 3.5
  2. Multiply: 3.5 × 20 = 70
  3. Check: Work backwards: 70 ÷ 20 × 100 = 350%.

Another method. As a proportion of part to whole: 350/100 = part/20, so part = 350 × 20 ÷ 100 = 70. Both methods always give the same answer.

In a spreadsheet: =350%*20. 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 350% is more than 100%, the answer is bigger than 20: it is 3.5 times 20.

Mark-ups: pricing an item at 350% of its $20 cost means selling it for $70.

Adding and taking away 350%

Increasing 20 by 350% gives 90. These do not cancel out: raising 20 by 350% and then lowering the result by 350% ends at -225, because the second 350% is taken of a bigger number.
