Adding Proper Fractions

This app explores adding proper fractions that may or may not start with common denominators using fraction circles.
  1. Create your fractions you want to add. You will get a message if your fractions are not proper, or if your common denominator is greater than 32.
  2. If you need common denominators, click "Equivalent Fractions." Drag the slider until you find a common denominator that will create equivalent fractions.
  3. Click "Combine Fractions" to add the two fraction circles.
  4. Write in your solution to see if you found the correct sum! You can provide either a mixed number or improper fraction for sums greater than 1.
