The following image was made from Subtract Fractions Designer:

The picture shows that the minuend is 3 5/6 units in length and the subtrahend is 2 1/3 units in length. The difference can be found by determining the distance from the end of the subtrahend to the end of the minuend. For example the distance from 2 1/3 to 3 is 2/3 units and the distance from 3 to 3 5/6 is 5/6 units. Just add 2/3 and 5/6 for the difference of 1 3/6 or 1 1/2 units. The difference must be entered as a mixed in lowest terms or a whole number.

When the program starts, you will be asked to identify the minuend in the first row and then the subtrahend in the second row. The program will continue when the minuend and subtrahend are correctly identified. You will then be asked to find the difference. The difference must be entered as a whole number or as a mixed number in lowest terms.

Follow the directions in the dialog box after pressing the <START> button. The <EXPLAIN> button may be pressed after you enter the subtrahend to see how to do the example.

After you enter the difference you may press the <REPORT> button. The report will ask for your name but you may submit a code for your name. This report will give same results as on the dialog box. The report may be printed or e-mailed.
