C. one twenty three million eight thousand six hundred three \[\]
D. one twenty three million eighty thousand six hundred \[\]

Answer 1

Hint: We recall the numeral form of a number, number name in words, and place value. We recall the Indian numbering system uses the comma separator after three digits from the right-hand side and after that every two digits towards the left-hand side. The international numbering system uses a comma after every 3 digits from the right-hand side. We follow the international numbering system to write the number in words. \[\]

Complete step by step answer:
We know that we can convert numbers written in words to numbers in standard or numeral form where we use symbols for 10 digits which are 0,1,2,34,5,6,7,8,9. We can write a number in the numeral form in words using the place value. \[\]
The place value of the digit of the number is from the right is one, ten, hundred, thousand, ten thousand. The international system of numbering after that has a place value ten thousand, hundred thousand, million, ten million, hundred million, billion up to ten places from the right. \[\]
We are given the number in numeral form as 123,080,603.
\[\begin{matrix}
   1 & 2 & 3 & 0 & 8 & 0 & 6 & 0 & 3 \\
   Htm & Tm & M & HTh & Tth & Th & H & T & O \\
\end{matrix}\]
We see that in the one’s place there is 3, in the ten’s place ether is 9 and in hundred’s place, three is 6. So can name the number as six hundred three. \[\]
We see in the thousand’ place there is 0 ten thousand‘s place there is 8 and in a hundred thousand places there is 9. So can extend the number of the number as eighty thousand six hundred three. \[\]
 We see that in millions place there is 1, in ten million’s place there is 2 and in hundred million’s place, there is 1. So can extend one hundred twenty-three million the number of the number as eighty thousand six hundred three. So the correct option is C. \[\]

Note:
 We note that in Indian Numeral System we use the words like lakh, ten lakh, crore and to represent place value after ten place value of ten thousand. We should always remember that 0 before the non-zero digit does not add place value but after the non-zero digit adds the place value. Here in this place problem in $ 080 $ the, 0 before 8 does not add any place value but the 9 after 8 adds places place value to make eighty.
