**Step 1:** Convert mixed numbers to improper fractions by multiplying the whole number by the denominator, then adding the numerator, while keeping the denominator the same.

**Step 2:** To add the improper fractions, they must have the like denominator. If they do not, find a common denominator, add the numerators together and the denominator remains the same.

**Step 3:** Convert the result to a mixed number by dividing the numerator by the denominator. The quotient becomes the whole number, the remainder becomes the new numerator, and the denominator stays the same.
