How to Convert a Fraction to a Decimal

By eHow Contributor

Learn how to easily convert any fraction to a decimal by following these simple steps.

It is important to first be able to recognize the numerator and denominator in a fraction before you can learn to change a fraction to a decimal. The numerator is always the number on top in a fraction. For example, in the fraction, 3/4, 3 is the numerator. The denominator is always the number on the bottom of a fraction and represents the number of parts into which one 'whole' is equally divided. If you think about a pizza that is cut into 4 slices, the 4 represents how many equal parts the whole pizza is divided into. In the fraction 3/4, 4 is the denominator. Now that you understand what the numerator and denominator is in a fraction, you can easily convert fractions into decimals.

To change a fraction to a decimal, simply divide the numerator by the denominator. So, to change 3/4 into a decimal, we would divide the numerator (3) by the denominator (4).

3/4 = .75

Let's look at another example. To convert 1/2 into a decimal, we would divide the numerator (1) by the denominator (2).

1/2 = .50

Any fraction can be converted into decimal form by simply following the above steps. There will be times when the fraction does not convert into an even decimal as in the fraction 2/3, but the conversion is done exactly the same.

2/3 = .667 (the repeating 6 in this example has been rounded to 7)

Or,

3/8 = .375
