Section M: Long Answer Questions

1. Explain the difference between the Indian and International number systems.

Answer: In the Indian number system, numbers are grouped using commas in a 3-2-2 pattern from right to left. The common terms used are thousand, lakh, crore, and arab. For example, 1 crore is written as 1,00,00,000.

In the International number system, numbers are grouped using commas in a 3-3-3 pattern from right to left. The common terms used are thousand, million, and billion. For example, 1 billion is written as 1,000,000,000.

2. Why do we use approximate values for large numbers?

Answer: We use approximate values because exact numbers are not always necessary. For example, instead of saying the population of a town is 76,068, we can say it is about 75,000. This makes large numbers easier to understand, compare, and remember. Approximation is useful in population, distance, height, money, and daily-life calculations.

3. How can familiar objects help us understand large numbers?

Answer: Large numbers can be difficult to imagine directly. When we compare them with familiar objects, we understand them better. For example, comparing the height of the Statue of Unity with a building helps us understand how tall it is. Similarly, comparing population with the capacity of buses or stadiums helps us understand how large the population is.

4. Why are lakhs and crores useful in daily life?

Answer: Lakhs and crores are useful because many real-life numbers in India are large. We use lakhs and crores while talking about population, money, distances, land area, government data, and business values. These terms make large numbers easier to read, write, and understand.
