Twelve thousand four hundred can be written as "12400". The number 12400 is used to signify a count or value that is equivalent to the term "twelve thousand four hundred" in mathematics. On a check, it is used to write out a value in words, such as 12400 rupees, which is written as "Rs. 12400 only" or "twelve thousand four hundred".

We use the number 12400 as part of a sentence while counting things. As an example, if you have recently saved Rs. 12400, you can write or say, "I have recently saved twelve thousand four hundred".

With reference to the right-hand-most digit, the place value of each constituent digit of the number is calculated in the decimal number system, and as you move away from the right-hand-most digit to the left, the place value grows as powers of 10.

Take note of the decimal number system's key characteristics listed below.

The digit at unit's or one's place is the digit that appears in the rightmost position of a number. {{10}^{0}} is its place value.

The tens place is the location of the digit of the number that is immediately to the left of the unit's place, and it is followed by the hundredth, thousandth, ten-thousandth, lakh's, crore's, ten crore's, and so on.

**The table below displays the corresponding place values as follows:**

Ten crore’s | crore’s | Ten lakh’s | lakh’s | Ten thousand’s | Thousand’s | Hundred’s | Ten’s | Unit or One’s |

{{10}^{8}} | {{10}^{7}} | {{10}^{6}} | {{10}^{5}} | {{10}^{4}} | {{10}^{3}} | {{10}^{2}} | {{10}^{1}} | {{10}^{0}} |

Ans: The place values of these 5 digits that make up the number 12400 are as follows.

In the number "12400", the unit place digit is "0".

In the number "12400", the tenth place digit is "0".

In the number "12400", the hundredth place digit is "4".

In the number "12400", the thousandth digit is "2".

In the number "12400", the ten thousandth digit is “1”.

The place value of each single digit can be observed as follows.

Ten thousand’s | Thousandth | Hundred’s | Ten’s | Unit’s or One’s |

1\times {{10}^{4}} | 2\times {{10}^{3}} | 4\times {{10}^{2}} | 0\times {{10}^{1}} | 0\times {{10}^{0}} |

The following can be proved mathematically.

\[\begin{align}

& 1\times {{10}^{4}}+2\times {{10}^{3}}+4\times {{10}^{2}}+0\times {{10}^{1}}+0\times {{10}^{0}} \\

& =1\times {{10}^{4}}+2\times {{10}^{3}}+4\times {{10}^{2}} \\

& =12400 \\

\end{align}

\]

In other words, 12400 is written as "Twelve thousand four hundred" since it equals 12000 and 4 hundreds.

Ans: Even numbers are those that divide exactly by two without producing a remainder. Even numbers include 2, 6, 10, 20, and 50 as examples.

Similarly, on dividing 12400 by two it results in the answer without remainder. It is clear that it is an even number as a result.

Ans: A whole number higher than one whose only factors are 1 and the number itself is referred to as a "prime number." The fact that 12400 may be divided by 1, 2, 5, 10, 25, and 50 proves that it is not a prime number. For a number to be regarded as a prime number, there must be exactly two factors.

Ans: The cardinal numbers are the ones that are used to count anything. The counting numbers that begin at 1 and grow successively are known as cardinal numbers; they are not fractions.

You may have noticed that whenever you get a natural or counting number, you refer to it as a cardinal number. The number 12400 obviously falls within the category of a cardinal number because it is a specific counting number.

Ans: Ordinal numbers are those that represent something or someone's exact location in a place. If the number of things or people is given as a list, ordinal numbers are used to identify a set of items or people. The adjective terms 1st, 2nd, 3rd, 4th, 5th, 6th, and so on are used to indicate something or someone's place in the order.

Thus, you can write “12400th” which indicates an ordinal number.
