Classification of Number System (PDF) The natural numbers are classified as follows: Natural Numbers. If you can divide a number by two, that number is even. Numerators and denominators form fractions, which are comprised of two integers. The denominator, the bottom number, shows how many parts make a whole.

1.

It will makes things crystal clear. In our number system we are representing the rational number in the form of fraction like a/b. classification of numbers.pdf - Free download as PDF File (.pdf), Text File (.txt) or read online for free.

Transcript. Rational numbers. Pi is renowned for going on forever. These numbers can’t be written as a simple fraction.

The different types of numbers in maths are: 1. They are complex numbers that are written as a real number multiplied by an imaginary unit (i).

Why do we give them names, like integers, irrational numbers, or negative numbers? Observation #1: Notice that √(9) is a natural number.

So just because these numbers are called “imaginary” doesn’t mean they aren’t useful. All odd numbers will end in 1, 3, 5, 7, or 9.

So, 17 divided by two is 8.5.

Natural numbers are those that are positive integers, although there is some debate as to whether natural numbers start at zero or one. An irrational number is any real number which cannot be expressed as a simple fraction or rational number.

Why do we give them names, like integers, irrational numbers, or negative numbers? Whole numbers do not have fractions or decimals. 1.5 = 3/2.
