How to write 0.65 as a fraction
Put the digits in a place value chart. The place of the last digit tells you the bottom of the fraction.
| Ones | Tenths | Hundredths |
|---|---|---|
| 0 | 6 | 5 |
The last digit is in the hundredths column, so 0.65 is 65 hundredths: 65/100.
Simplify by dividing the top and bottom by the same number. In one go, divide by the highest common factor (the biggest whole number that divides both exactly), 5: 65/100 = 13/20.
13 and 20 share no factor except 1, so 13/20 is the simplest form.
As a percentage, 0.65 = 65%: multiply by 100, which moves each digit two places to the left.
