Answer 2

The comparison of two quantities is known as ratio.

Explanation:

• The relation between two quantities can be determined by ratios and it compares the quantities.
• By dividing one quantity by another, the ratio can be obtained and it compares two similar quantities.
• Ratio is an abstract number, since it determines the relation and comparison of quantities.
• The symbol for ratio is ":" and the ratio cannot be determined, if the two quantities have different units.
• For example, to find the ratio of 4 km to 400m, we need to convert the numbers into same units.
• 1 km = 1000 m, hence 4 km = 4000 m.
• Therefore, the ratio between 4000 m : 400 m is 10 : 1.
