What you need to know

  • To turn a mixed number into an improper fraction, multiply the whole number by the denominator and add the numerator.
  • 1½ becomes 3/2 and 4⅔ becomes 14/3, then the fractions can be added like any others.
  • To turn an improper fraction back, divide: 37/6 is 6 remainder 1, so 6⅙.
  • The same converting steps work for subtracting mixed numbers, such as 3⅓ − 2¼ = 1 1/12.
