Remember!

To add or subtract mixed numbers, we can:

  • split each mixed number into a sum of its whole part and fractional part
  • add or subtract the whole parts and the fractional parts separately
    • add the numerators and copy the denominator of like fractions
  • combine the two parts of the answer into a single fraction, a whole number or mixed number
