Note: Any mixed numbers must be made improper first.
1) Multiply the denominators to get the denominator of the answer.
2) Multiply the diagonals (see video).
3) Add the numbers from step 2 to get the answer's numerator.
Note: The student may have to simplify the answer, but at least it is a simple and consistent way to get the right answer!
