Finding the Ratio of Two Quantities

We must express both quantities in the same unit of measurement to find the ratio of two quantities in its simplest form.


Example 2

Find the ratio of 50 centimetres to 2 metres in its simplest form.

Solution:

2 m = 200 cm

Ratio of 50 cm to 2 m = 1 : 4

Note:

We can use ratios to compare more than two quantities conveniently.  Fractions are not usually suitable for this.


Key Term
