When the numerator and denominator have the same value, the fraction is equal to one whole.
If the numerator is less than the denominator, the fraction is less than one whole.
Fractions that have numerators and denominators with the same values are also equal to each other.

Pupils may think that fractions with a higher value numerator are larger in size.

Show pupils images where fractions with the same numerators and denominators are equal in size (e.g. nine-ninths is equal to three-thirds).
