Question

Write the number name of each in the Indian & International system of numeration:
a) 90703006
b) 37502093

Answer 1

Hint: We solve this question by using the concept of the number system. We name these given numbers based on the Indian & International system convention of naming numbers. We explain what each of these are before solving this question. Then we represent each of the numbers given in the question in terms of these two naming systems.

Complete step by step solution:
In order to solve this question, let us explain the concept of Indian & International system of numeration. The naming convention from the smallest to largest digit from the right-hand side to the left-hand side is given as: ones, tens, hundreds, thousands, and ten-thousands. It is the same for these two conventions till this point. Beyond this they differ such that for the Indian system of numeration is given by lakhs, ten-lakhs, crores, ten-crores, etc. For the International system of numeration, it is represented as hundred-thousands, millions, ten-millions, etc.
Using this concept, we represent the following numbers in terms of words. Considering the first option, 90703006 we name it as follows:
Indian system- Nine crore seven lakh three thousand and six
International system- Ninety million seven hundred three thousand and six
Similarly, we represent the second number 37502093 as follows:
Indian system- Three crore seventy-five lakh two thousand and ninety-three
International system- Thirty-seven million five hundred two thousand and ninety-three
Hence, we have represented the number name of each of the two numbers given in the Indian & International system of numeration.

Note: We need to know the basic concepts of naming numbers in both the systems to solve such questions. An important point to note is the difference between these two systems. This is represented by the fact that for the Indian system of numeration, they are represented in terms of lakhs and crores, whereas for the Intentional system of numeration, they are given in terms of millions and billions.
