The first step when changing a mixed number to an improper fraction is to multiply the whole number part by the denominator and then add the numerator. This gives you the new numerator for the improper fraction. The denominator remains the same.

So, if we break it down:

  1. Multiply the whole number part by the denominator.
  2. Add the numerator to that product to get the new numerator.
  3. The denominator remains unchanged.

Therefore, your primary operation is multiplying the whole number part by the denominator and then adding the numerator to it.
