Ordinal numbers meaning states that the numbers which provide us with the exact position of an object are known as the ordinal numbers. Ordinal numbers notifies the position of an object instead of their quantity.

For Example:

The picture below depicts different floors in a building. We typically use ordinal numbers to describe their position.

The numbers 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th, and 10th explains the position of different floors in the building. Thus, all of them are ordinal numbers.

There is a clear difference between cardinal and ordinal and that you will get the complete idea about from the following:-

Cardinal number here in this example is 4 that represents the total number of cars. However, if we want to tell about the position of the yellow car, then the ordinal number is 3rd.

There are basically two approaches to measuring utility, details of which are provided below:

a) Cardinal Utility.

b) Ordinal Utility.

However, remember that these two demand analysis approaches are not in competition with each other, but during the assessment of consumer behaviour, they depict two levels of sophistication.

FAQ (Frequently Asked Questions)

1. What is Meant by Decimals in Cardinal Numbers?

Answer: Decimals are the mathematical numbers that typically comprises two parts namely, a whole number part and a fractional part of a number isolated by a decimal point. For example, 10.2 is a decimal number. While using the cardinal number for decimals:

2.7 → two point seven

5.36 → five point three six.

2. What is Meant by Roman Numbers?

King George XI → King George Eleven

Louis XIV → Louis the Fourteenth

Elisabeth III → Elisabeth the Third

3. What is Meant by Fractions and Decimals?

Answer: Use fractions for the ordinal number for the denominator:

2/4 → two forth

1 3/5 → one and three fifths

Exceptions:

1/2 → one half
