FAQs on Numbers in India and International System Video Lecture - Mathematics Class 6 ICSE

1. What are the main differences between the Indian Number System and the International Number System?

Ans. The Indian Number System groups numbers in lakhs and crores, while the International Number System uses thousands and millions. In the Indian system, numbers are divided into groups of two after the first three digits (e.g., 1,00,000 for one lakh), whereas in the International system, they are grouped in threes (e.g., 100,000 for one hundred thousand).

2. How do you read large numbers in the Indian Number System?

Ans. In the Indian Number System, large numbers are read by breaking them into groups of two and three. For example, the number 12,34,567 is read as "Twelve lakh, thirty-four thousand, five hundred sixty-seven."

3. Can you convert numbers easily between the Indian and International Number Systems?

Ans. Yes, you can convert numbers by understanding the place values in both systems. For example, the number 5,00,000 in the Indian system is equivalent to 500,000 in the International system. You can convert it by rearranging the groups and adjusting for the different naming conventions.

4. What are some examples of numbers in both systems?

Ans. Examples include: - 1,00,000 (one lakh) in the Indian system is 100,000 in the International system. - 10,00,000 (ten lakh) in the Indian system is 1,000,000 in the International system. - 1,00,00,000 (one crore) in the Indian system is 10,000,000 in the International system.

5. Why is it important to learn both number systems?

Ans. Learning both number systems is important because it helps in understanding and communicating numerical data in different contexts, especially in a globalized world where both systems are commonly used. It enhances mathematical skills and aids in better comprehension of financial documents, statistics, and academic materials.
