Solve problems involving increasingly harder fractions to calculate quantities, and fractions to divide quantities, including non-unit fractions where the answer is a whole number

What this means, in plain words

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

This is problem solving: the maths is met inside a situation, so the first job is working out which operation the question is asking for.

Multiplication is repeated addition of equal groups. Division shares a total into equal groups, or works out how many groups fit.
