Adding Fraction

[Fu-Kwun Hwang]

There are 3 Simple Steps to add fractions:

   Step 1: Make sure the bottom numbers (the denominators) are the same
   Step 2: Add the top numbers (the numerators), put the answer over the denominator.
   Step 3: Simplify the fraction (if needed).

The following simulation try to help you understand what it means!
