This program is similar to the previous program ADD UNLIKE FRACTIONS except that theaddends may be mixed numbers and the sum must be written as a mixed number and in lowest terms.

See the program MIXED NUMBERS for information on writing fractions in mixed form.

See the program RENAME TO LOWEST TERMS for information on writing fractions in lowest terms.

The above illustration shows that the addends are written with a common denominator 12. The numerators 10 and 9 are then added for a numerator of 19 in the sum. The sum 2 19/12 can be simplified to 1 4/12 in mixed form. The 1 in 1 7/12 is added to 2 for a simplified sum of 3 7/12 The sum must be entered in in lowest terms. So in the above example, only 3 7/12 is acceptable.

You may prefer to work vertically:

Or you may prefer to write each addend in fraction form first:

In many examples, the sum may be found by visually combining the two addends.

In the above example, the sum (3 7/12) must be entered as a mixed number and 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 second addend to see how to do the example.

After you enter the sum 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 the same results as on the dialog box. The report may be printed or e-mailed.
