Show transcript
Rods or number lines can be used to support subtracting fractions from whole or mixed numbers. Mixed numbers can be expressed as improper fractions to aid subtraction. If an answer to a calculation is an improper fraction, this should be expressed as a mixed number. Improper fractions can be subtracted in the same way as proper fractions.
