Hello sir

Sir why decimal no's are also not a part of no' system because in no. system there are natural, whole, integers, rational, irrational, real but why decimal no's are not a part of no. system

My second question>>>>> Sir commonly i wnat to ask that 0 to till infinity numbers are there but why we have classified then into natural whole, integer, rational, irrational real numbers.

Hi Apsara,

Decimal numbers are a way of representing a number, it is not the number itself. In principle, any number that you can write in decimal form is a real number.

Naturals, integers, rationals, and reals exhibit different sets of properties. By classifying them, it allows us to easily separate them by properties. Furthermore, there are certain applications where being able to refer to these categories of numbers is extremely convenient.

Thanks for asking,

Azeem
