Recognise mixed numbers and improper fractions and convert from one form to the other and write mathematical statements > 1 as a mixed number [for example, 2/5 + 4/5 = 6/5 = 1 1/5 ]

What this means, in plain words

An improper fraction is top-heavy, worth more than one whole. A mixed number writes the same amount as a whole number and a fraction side by side.

Converting means saying the same amount in a different unit, such as 1,500 metres as 1.5 kilometres.

A fraction describes part of a whole, or part of a set, once the whole has been split into equal pieces.
