How to order fractions using one of two methods.

How to Order Fractions

To arrange a list of fractions in ascending or descending order, it may help to use one of two methods; Decimals or Like Denominators.

The decimal method involves converting each fraction to a decimal, and then sorting by the decimals.

To convert a fraction to a decimal, you divide the numerator by the denominator. For example, the fraction 1/2 becomes the decimal 0.50 (1 divided by 2 = 0.50).

The second method for sorting fractions involves converting all fractions so they share the same denominator and then sorting by their numerators.

To convert a list of fractions with unlike denominators into fractions with like denominators, you first find the lowest number that all denominators will divide into evenly (Least Common Multiple or LCM).

Once you know the least common denominator for the group of fractions, you then convert each fraction by following these steps:

  1. Divide the LCD by the denominator.
  2. Multiply the numerator by the result in step #1. The result becomes the new numerator.
  3. The LCD becomes the new denominator.

Ordering Fractions Examples

Example #1: Fractions Only
1/121/48/94/62/3

Here is how to order the fractions using two different methods.

Method #1: Convert fractions to decimals and then sort by the decimals.

Convert each fraction to a decimal by dividing the numerator by the denominator.

Method #2: Convert fractions to like denominators, and then sort by their numerators.

To convert fractions to like denominators, start by finding the least common denominator (LCD) of all denominators (lowest number all 5 denominators divide into evenly), which in this case is 36. Next, for each fraction, divide the LCM by the denominator and then multiply that result by the numerator to get the converted numerator. Finally, use the LCM as the new denominator.

4/636 / 6 * 4 = 2424/36

Example #2: Fractions and Mixed Numbers
1 6/71/91 1/31 1/82/5

Here is how to order the fractions and mixed numbers using two different methods.

Since one or more of your entries are mixed numbers, convert them to fractions by multiplying the denominator by the whole number, and then adding that result to the numerator to get the converted numerator.

Method #2: Convert fractions to like denominators, and then sort by their numerators.

To convert fractions to like denominators, start by finding the least common denominator (LCD) of all denominators (lowest number all 5 denominators divide into evenly), which in this case is 2520. Next, for each fraction, divide the LCM by the denominator and then multiply that result by the numerator to get the converted numerator. Finally, use the LCM as the new denominator.

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.
