When working with mixed numbers it is almost always easier to convert them to improper fractions first, do the whatever (with the improper fraction just like an ordinary fraction) and convert any final improper fraction into a mixed number.

To convert a mixed number to an improper fraction, multiply the whole number by the denominator and add the numerator to form the new numerator and keep the denominator the same.

For example: 2 3/7 → (2x7+3)/7 = 17/7

To convert an improper fraction to a mixed number divide the numerator by the denominator to get a whole number quotient and a remainder. The whole number quotient is the whole number and the remainder is put as the numerator over the original denominator as the fraction.

For example: 17/7 → 17 ÷ 7 = 2 r 3 → 17/7 = 2 3/7
