Fraction to Decimal Calculator FAQ
What does this fraction to decimal calculator do?
This calculator converts common fractions and mixed numbers to decimals, and also converts decimals back to fractions. It is designed for both fraction to decimal and decimal to fraction use.
How do you convert a fraction to a decimal?
Divide the numerator by the denominator. For example, 3/4 = 0.75 and 1/8 = 0.125. For a mixed number such as 1 2/5, first convert it to an improper fraction or evaluate it as 1 + 2/5 = 1.4.
How do you convert a decimal to a fraction?
Write the decimal as a fraction over a power of 10 and simplify. For example, 0.75 = 75/100 = 3/4. A repeating or long decimal may not always reduce to a short, practical fraction automatically.
Can this calculator handle mixed numbers?
Yes. Enter the whole part together with the numerator and denominator. For example, 1 2/5 converts to 1.4.
Example: what is 1 2/5 as a decimal?
The mixed number 1 2/5 equals 1 + 2/5, which is 1.4.
