2/7 as a percentage
2 ÷ 7 × 100 never comes out exactly: it is 28.571428571428...%, which is 28 4/7%.
The answer
2/7 = 28 4/7%
That is 28.571428%, where the group 571428 repeats for ever, or 28.6% to 1 decimal place.
How to turn 2/7 into a percentage
Per cent means out of 100, so a percentage is a fraction with a bottom of 100.
Extension: an exact answer can include part of a per cent. For example, 33 1/3% means 33 per cent and one third of another per cent.
7 does not go exactly into 100, so there is no whole-number way to make the bottom 100. Go through the decimal instead:
- Divide the top by the bottom: 2 ÷ 7 = 0.285714, where the group 285714 repeats for ever.
- Multiply by 100, which moves every digit two places to the left: 28.571428%, where the group 571428 repeats for ever.
To write it exactly, divide 200 by 7 and keep the remainder: 200 ÷ 7 = 28 remainder 4. The remainder is 4/7 of a per cent, so 2/7 = 28 4/7%.
Rounded to 1 decimal place, 2/7 is 28.6%. To the nearest whole per cent, it is 29%.
2/7 as a fraction, decimal and percentage
| Fraction | Decimal | Percentage |
|---|---|---|
| 2/7 | 0.285714, where the group 285714 repeats for ever | 28 4/7% |
Multiply the top and bottom by the same number and the fraction keeps its value: 2/7, 4/14, 6/21, 8/28 and 10/35 are all equal.
