1/12 as a percentage

1 ÷ 12 × 100 never comes out exactly: it is 8.333...%, which is 8 1/3%.

The answer

1/12 = 8 1/3%

That is 8.3%, where the 3 repeats for ever, or 8.3% to 1 decimal place.

How to turn 1/12 into a percentage

Per cent means out of 100, so a percentage is a fraction with a bottom of 100.

12 does not go exactly into 100, so there is no whole-number way to make the bottom 100. Go through the decimal instead:

  1. Divide the top by the bottom: 1 ÷ 12 = 0.083, where the 3 repeats for ever.
  2. Multiply by 100, which moves every digit two places to the left: 8.3%, where the 3 repeats for ever.

To write it exactly, divide 100 by 12 and keep the remainder: 100 ÷ 12 = 8 remainder 4. The remainder is 4/12 of a per cent, which simplifies to 1/3, so 1/12 = 8 1/3%.

Rounded to 1 decimal place, 1/12 is 8.3%. To the nearest whole per cent, it is 8%.
