Expert Answer:

A ratio is a comparison of two quantities. We denote ratio using symbol ': '.

Example- Find the ratio of 60 cm to 1.2 m.

Solution: The quantities are not in the same units. Therefore we have to convert them in to same units.

1.2 m = 1.2cross times100 = 120 cm

The required ratio can be written as 60: 120 equals 60 over 120 equals 1 half

Therefore, the required ratio is 1: 2.
