How to write 0.2 as a fraction
Put the digits in a place value chart. The last digit tells you the bottom of the fraction.
| Ones | Tenths |
|---|---|
| 0 | 2 |
The last digit is in the tenths column, so 0.2 is 2 tenths: 2/10.
Simplify by dividing the top and bottom by the same number. In one go, divide by the highest common factor, 2: 2/10 = 1/5.
1 and 5 share no factor except 1, so 1/5 is the simplest form.
As a percentage, 0.2 = 20%: multiply by 100, which moves each digit two places to the left.
