How Is The Decimal Number System Designed?

The design of the decimal number system is described under the following heads.

• It is an organized arrangement of numbers employing the “indices of 10” for indicating the place values of the digits of every number.

• On knowing the unique place value or the position of every single digit of the number, you can express a number in words.

• To determine the place value of any digit in a decimal number, the reference from the rightmost digit is universally accepted. The place value, basically, increases by “a power of 10” as you go towards the “left-hand side” from the first digit in the right-hand side of the number.

Can You Write "100" In Words?

As we find no unit of measurement after or before ‘"100". So, evidently, "100" represents a unitless number only.

You get only 3 digits in the number "100".

Observe that the decimal number system reveals the following information about the place values of these 3 digits of "100".

• The unit’s place in the number "100" is "0".

• The ten’s place in the number "100" is "0".

• The hundredth place in the number "100" is "1".

Mathematically you can write the following

\[\begin{align}

1\times {{10}^{2}}+0\times {{10}^{1}}+0\times {{10}^{0}} \\

=1\times {{10}^{2}} \\

=100 \\

\end{align}\]

Now, you see that there is only one non-zero digit “1” in the hundredth place of "100"; while its ten’s place and unit’s place have digits 0, and 0.

Thus, you can represent "100" in words as per the rules of the decimal number system in this way.

"100" is “One Hundred” in words.

Can You Write "100 Rupees” In Words?

In the term "100 rupees” you can, easily, identify that the number "100" is being immediately followed by the unit "rupees".

Now first write the number "100” in words. Then put the unit "rupees".

So, you get that "Rs. 100” is “One Hundred rupees” in words.

Can You Say If "100" Is An Even Or An Odd Number?

You are aware that when “2” can divide any number completely, without leaving any remainder, you declare that number as an “even number”.

On the other hand, if you get any number that leaves any remainder on being divided by “2”, it is an “odd number”.

Here, when you divide the number "100" by 2, there remains no remainder as evident from the following division.

\[100\div 2=50\]

Therefore, it can be concluded that “100” is not an odd number. It is an “even number”.

Is The Number "100" A Perfect Square?

Note that a “perfect square” is such a number, that you can write that number as the product of two equal integers.

Expand the number “100” in the following way.

\[\begin{align}

100={{2}^{2}}\times {{5}^{2}} \\

={{\left( 2\times 5 \right)}^{2}} \\

={{10}^{2}}

\end{align}\]

See that "100" is exactly equal to the product of two equal integers. Hence, you infer that the number "100" is, definitely, a “perfect square”.

Do You Know If "100" is A Prime Or A Composite Number?

Any particular number that on factorizing yields only two factors (“1”, and the number itself), is a “prime number”.

Conversely, when you find a number reflecting more than two factors, you call it a “composite number”.

Here, you observe the following way.

\[\text{Factors of 1}00=\ 1,\ 2,\ 4,\ 5,\ 10,\ \ldots \ 100\]

So, you find that the number of factors of "100" is more than two. This follows that "100" is not a prime number, but is, definitely, a “composite number”.

Is The Number "100" Cardinal?

Whenever you find any natural or counting number, you can, definitely, call it a “cardinal number”.

Here, the number "100" is, definitely, a specific counting number, so it falls under the category of a “cardinal number”.
