How the Decimal to Fraction Calculator works
The decimal is written over a power of 10 (one zero for each decimal place), then both parts are divided by their greatest common factor.
0.375 = 375 ÷ 1000
Divide top and bottom by GCF(375, 1000) = 125 → 3/8
Step-by-step calculation
- 1Enter the decimal.
- 2Write it over a power of 10.
- 3Divide top and bottom by their GCF.
Worked example
0.375 = 375/1000 = 3/8. And 2.75 = 275/100 = 11/4 = 2 3/4.
