How to write twelve thousand twelve hundred and twelve?

Hint: In this question, we are given a number in words. We have to write in numbers. We will use the fact that thousand stands for \[1000\] and hundred stands for \[100\] . We will simply multiply the given magnitude by the conversation digit place value.
To answer this question, we can use the Indian Numeral System. The Indian numeral system (also known as the numeration system) is a writing method for representing numbers that was developed in India.
We count in ones, tens, hundreds, thousands, ten thousand, lakhs, ten lakhs, and crores when we apply the Indian number system. Then we will simply add the numbers obtained to get the number in figure.

Complete step by step solution:
Considering the given question, we have to write the given number from words to figures.
We know that the value of a thousand in the figure is \[1000\]. And the value of hundred in figure is 100. So, we simply multiply the magnitude by their given value.
Hence twelve thousand can be written as \[12 \times 1000 = 12000\]
And twelve hundred can be written as \[12 \times 100 = 1200\]
Twelve can be written as \[12\]
Now we take sum of these numbers in figure
i.e., \[(12000 + 1200 + 12)\]
On adding digits from right to left, we get
\[12000 + 1200 + 12 = 13212\] .
Hence twelve thousand twelve hundred and twelve can be written as \[13212\] .
So, the correct answer is “\[13212\]”.

Note: To write the given numbers from word to figures or vice-versa, we simply use the place value of that given magnitude of number.
Place value is the value of each digit in the number. For example, the place value of \[5\] in \[5460\] is \[5\] thousand.
Face value is the numeral or magnitude of the digit in the given number. For example, the face value of \[5\] in \[5460\] is \[5\] itself.
Thus, any number can be written as the sum of place value. For example, \[54 = 50 + 4\] and in words written as fifty-four. Similarly, \[5460 = 5000 + 400 + 60 + 4\] and in words written as five thousand four hundred and sixty-four.
