How the conversion works

A fraction is another way to show equal parts of one whole.

  1. Start with the fraction

    1 1/2 = 3/2

  2. Convert to an improper fraction, then divide

    3 ÷ 2

  3. Read the decimal result

    1.5

How to convert a mixed fraction to a decimal

  1. Keep the sign with the whole mixed number. For example, −2 1/4 is negative 2 1/4, not −2 + 1/4.
  2. Multiply the absolute whole number by the denominator.
  3. Add the numerator to the result.
  4. Divide that total by the original denominator.

Example: Convert 1 3/4 to a decimal

For 1 3/4, the whole number is 1, the numerator is 3, and the denominator is 4.

Therefore, 1 3/4 = 1.75.

Example: Convert −2 1/4

Apply the negative sign to the whole result: (2 × 4 + 1) ÷ 4 = 9 ÷ 4 = 2.25, so −2 1/4 = −2.25.

Can you use the calculator above?

Yes. Enter the whole number, numerator, and denominator directly. The calculator also shows the equivalent improper fraction, a bounded visual, and the precision note for repeating decimals.

Frequently Asked Questions

How do you convert a fraction to a decimal?

Divide the numerator by the denominator. For example, 3 divided by 4 equals 0.75.

Can every fraction be written as a terminating decimal?

No. Some fractions produce repeating decimals, such as 1/3 = 0.333... .

What happens if the denominator is zero?

A fraction with a zero denominator is undefined, so it cannot be converted to a valid decimal.

Can I convert an improper fraction?

Yes. Divide its numerator by its denominator just as you would with any other fraction.

How do I convert a mixed number to a decimal?

Convert the fractional part to a decimal, then add it to the whole-number part. Account for the sign when working with negative mixed numbers.
