How to Convert Expanded Form to Standard Form in Large Numbers
FAQs on Place Value and Normal Form Worksheet for 9-Digit Numbers (Class 6)
1. What is the place value of 9 digits?
The place value of a 9-digit number depends on whether you are using the Indian or International system. Both systems define the position and value of each digit from right to left, extending into large numbers like Crores or Hundred Millions.
- Indian System: The nine places are Ones, Tens, Hundreds, Thousands, Ten Thousands, Lakhs, Ten Lakhs, Crores, and Ten Crores.
- International System: The nine places are Ones, Tens, Hundreds, Thousands, Ten Thousands, Hundred Thousands, Millions, Ten Millions, and Hundred Millions.
2. How to write 9-digit numbers in normal form?
To write a 9-digit number in normal form (also called standard form), you combine the values from the expanded form and write the digits in their correct place value order. You must place a zero as a placeholder for any missing place value.
For example, to convert 30,00,00,000 + 5,00,00,000 + 70,000 + 200 + 9 to normal form:
- Identify the highest place value (Ten Crores).
- Fill in each digit: 3 in Ten Crores, 5 in Crores.
- Use zeros for missing places (Ten Lakhs, Lakhs, Ten Thousands, Thousands).
- Place remaining digits: 7 in Ten Thousands, 2 in Hundreds, 9 in Ones.
- The normal form is 35,00,70,209.

7. What age group is it best for?
This worksheet is specifically designed for Class 6 students, typically aged 11–12 years. It aligns with the syllabus for this grade level and is also useful for Grade 7 students who need to revise their understanding of place value and large numbers.
8. What is the difference between normal form and expanded form?
Normal form and expanded form are two ways to represent the same number. Understanding the difference is a key part of learning place value.
- Normal Form: This is the standard way we write numbers using digits (e.g., 45,67,89,123). It is a compact representation.
- Expanded Form: This shows the number as a sum of the place value of each of its digits (e.g., 40,00,00,000 + 5,00,00,000 + 60,00,000 + 7,00,000 + 80,000 + 9,000 + 100 + 20 + 3).
This worksheet provides practice in converting from expanded to normal form.
9. Can I use this worksheet digitally on a tablet?
