How do I put fractions in order?


Quick Answer

To put fractions in order, first make sure that the denominators, or bottom numbers, are the same. Use the rule of least common denominator (LCD) as necessary. When the denominators are the same, put the fractions in order according to the numerators, or top numbers.

  1. Look at the denominators

    Begin putting fractions in order by looking at the denominators. If all of the fractions have the same denominator, you do not perform any conversions and can move on to the next step.

  2. Order by numerator

    If all of the denominators are the same, put the fractions in order by the numerators. For example: one-eighth, two-eighths, three-eighths, four-eighths and so on.

  3. Use the LCD rule to convert fractions

    If the denominators are different from one another, find the least common denominator, and convert the fractions so all have the same denominator. For example, the least common denominator of one-half and two-sixths is six. The equivalent fractions are three-sixths and two-sixths.

  4. Order the fractions by numerator

    Order the fractions by numerator once you have created fractions with the same denominator. Using the example in the previous step, the correct order would be two-sixths and three-sixths. Use the original fractions, and the correct order is two-sixths and one-half.
