Question

Write the following numbers in words: $19,09,09,900$.

Answer 1

Hint: In this question, we are given a number and we have been asked to write the number in words. As we can notice from the commas, the number is written in Indian system of numbers. Start by writing the places above the number and then expand the number as per their places.

Complete step-by-step answer:
We are given a number $19,09,09,900$ in Indian Numeral System and have been asked to write the number in words. Before writing in words, let us first write their places.

Now, we can expand the number starting from left as per the places written above them.
It will be – Nineteen crores nine lakh nine thousand and nine hundred.

Nineteen crores nine lakh nine thousand and nine hundred is the word form of 19,09,09,900

Note: 1) It is always advisable to write the places above the number as it makes it easier and reduces the possibility of any mistake.
2) We could easily recognize that the number written was in Indian Numeral system and not in the International system because of the commas.
The International system is written in this way:
It starts with – ones, tens, hundreds, thousand, ten thousand, hundred thousand, million, ten million, hundred million, billion and so on ...
In this system, commas come after intervals of three.
The Indian Numeral system is written in this way:
It starts with - ones, tens, hundreds, thousand, ten thousand, lakhs, ten lakhs, crores, ten crores and so on ..
In this system, commas first come after a hundred and then after intervals of two.
