Enter a decimal number and get it automatically converted to a simplified fraction, in its simplest form.
The method involves counting the number of decimal places, setting the number without the decimal point as the numerator, and using a power of ten (10, 100, 1000 …) as the denominator based on the number of decimals. The fraction is then simplified by dividing the numerator and denominator by their greatest common factor:
Here, 0.75 has two decimals, so the denominator becomes 100 (10²), and the numerator becomes 75. Both 75 and 100 can be divided by 25, so the fraction simplifies to 3/4.
Not perfectly precisely. The calculator uses the number of decimals actually entered in the field, so a repeating decimal must be rounded to a specific number of decimals before conversion — giving an approximate, not exact, fraction.
A simplified fraction shows the same value with the smallest possible numbers, and is easier to read and compare. The simplification happens by dividing the numerator and denominator by their greatest common factor.
Yes — divide the numerator by the denominator to get the decimal number. Our fraction calculator also shows the decimal number automatically when you calculate with fractions.
