The answer
0.75 = 3/4
How to write 0.75 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 | 7 | 5 |
The last digit is in the hundredths column, so 0.75 is 75 hundredths: 75/100.
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), 25: 75/100 = 3/4.
If you cannot spot 25, smaller steps get there too:
- Divide by 5: 15/20
- Divide by 5: 3/4
3 and 4 share no factor except 1, so 3/4 is the simplest form.
As a percentage, 0.75 = 75%: multiply by 100, which moves each digit two places to the left.
To check, divide back: see 3/4 as a decimal and 3/4 as a percentage.
