Adding Fractions Shortcut- Smiley Face Method
Use this shortcut to add fractions easily.
Steps of the Smiley Method
1. Multiply the denominators
2. Starting with the fraction on the left, cross multiply the numerator times the denominator.
3. Add the two solutions from step 2 for your numerator.
4. Reduce if possible.
This shortcut works on all proper and improper fractions, and with mixed fractions all you need to do is to convert the fraction to an improper fraction.I call the shortcut the "smiley method" because you multiply the denominators and the two fractions looks like a face that is smiling.
