What is a fraction?

Fractions are made up of a numerator and a denominator.

The numerator is the top number. It tells us how many parts we have.

Fourths or Quarters which is represented as 1/4, this means one out of four equal parts.

Eighths which is represented as 1/8, this means one out of eight equal parts.
