ones, tens and hundreds
b)
ones
c)
ones, tens, hundreds and thousands
d)

| | Sudhir Mehta answered |
In the International system of numeration, all the periods have three place values each. Since each period has three place values, so to write a number with the help of comma(s), we have to put a comma after every three digits from the right.
We are asked about the places in one’s period. Since it is the first period, starting from the right we have ones, tens and hundreds
So, the correct answer is “Option B”.

Understanding the Place Value Chart for Five-Digit Numbers
When representing a five-digit number, the place value chart is structured to show the value of each digit based on its position. The correct answer is option A, which states that the chart is divided into two periods: Ones and Thousands. Let's explore this in detail.
1. Two Main Periods
- The place value chart is organized into two main periods:
- Ones Period
- Thousands Period
2. Structure of Each Period
- Ones Period: This includes three positions:
- Ones (1s)
- Tens (10s)
- Hundreds (100s)
- Thousands Period: This includes two positions:
- Thousands (1,000s)
- Ten Thousands (10,000s)
3. Example of a Five-Digit Number
- For instance, in the number 43,215:
- The 4 is in the Ten Thousands place.
- The 3 is in the Thousands place.
- The 2 is in the Hundreds place.
- The 1 is in the Tens place.
- The 5 is in the Ones place.
4. Importance of the Structure
- Understanding this structure helps in:
- Identifying the value of each digit.
- Performing addition or subtraction correctly by aligning numbers based on place value.
- Comprehending larger numbers as they are broken down into manageable parts.
By organizing the chart into these two periods, students can easily visualize and understand the significance of each digit in a five-digit number.
