Answer 1

Hint: In this question, we are given an expression of number in words and we have to find its expression in numeral. Since, a given number is stated in the international system of numeration so we will first try to understand the international system of numeration and then we will use it to find numeral of the given number in words.

Complete step-by-step answer:
In the international system of numeration, we have values of places from right to left as one, ten, hundred, thousand, ten thousand, hundred thousand, million, ten million, hundred million and so on. Also, commas are put after every three places from the right.
Here, we are given numbers as ninety million ninety thousand ninety. As we can observe, there will be 0 at one place, 9 at ten places. Similarly, there will be 0 for hundreds place, 0 for thousands place and 9 for ten thousands place. Since, there is no term for hundred thousand place, therefore there will be 0 for hundred thousand place, 0 at one millions place and 9 at ten millions place.
Thus, we can obtain a number corresponding to ninety million ninety thousand ninety as 90,090,090.
Hence, option B is the correct answer.

So, the correct answer is “Option B”.

Note: Students should be careful in putting values of numbers as there are a lot of zeroes involved. For simplification, students can also solve this type of sums with the help of place value chart given below:

Millions	Thousands	Ones
Hundred Million	Ten Million	Million	Hundred Thousand	Ten Thousand	Thousand	Hundred	Tens	Ones
100,000,000	10,000,000	1,000,000	100,000	10,000	1,000	100	10	1
	9	0	0	9	0	0	9	0

There could be numbers in billions also, for that, the list goes on as one billion, ten billion and hundred billion and so on.
