To build an equivalent fraction, multiply the numerator and denominator by the same number. If adding two mixed numbers would give you an improper fraction as part of your result, you’ll need to carry; if subtracting two mixed numbers would give you a negative fraction as part of your result, you’ll need to borrow.
