Ratio

A ratio is a comparison of two quantities. The ratio \(\textcolor{colordef}{2}\) to \(\textcolor{colorprop}{3}\) can be expressed as the fraction \(\dfrac{\textcolor{colordef}{2}}{\textcolor{colorprop}{3}}\).

The fraction of red apples to all the apples is \(\dfrac{3}{4}\).

The fraction of red apples to all apples is \(\dfrac{2}{4}\), which simplifies to \(\dfrac{1}{2}\) (half are red).
