Sol:
Here are the values of each number:
The place value of 5 is 500. (Hundred)

Sol: 
Here are the values of each number:
The value of 0 is 000. (Hundred)

Sol: Arranging numbers in ascending order means putting them in order from the smallest to the largest. Here's a step-by-step guide:

• Start with the Smallest Number: Identify the smallest number in the given set.
• Move to the Next Smallest: Look for the next smallest number in the remaining set.
• Continue the Process: Repeat the process, identifying the next smallest number until you've accounted for all the numbers in the set.
• Write in Ascending Order: Write down the numbers in the order you found them, from the smallest to the largest.
  (a) 7038, 7304, 7308, 7348
  (b) 4256, 4325, 4526, 4569

Sol: In the Indian numbering system, numbers are divided into place values such as Lakhs (L), Ten Thousands (TT), Thousands (T), Hundreds (H), Tens (T), and Ones (O). Each place has a specific value depending on its position in the number. When we place digits in these columns, it shows the value each digit represents in the number. Let’s break down each example:

(a) 3,50,008:

• The digit 3 is in the Lakhs place, representing 3,00,000.
• The digit 5 is in the Ten Thousands place, representing 50,000.
• 0 is in both the Thousands, Hundreds, and Tens places, showing there are no thousands, hundreds, or tens.
• The digit 8 is in the Ones place, representing 8.

(b) 9,50,004:

• The digit 9 is in the Lakhs place, representing 9,00,000.
• The digit 5 is in the Ten Thousands place, representing 50,000.
• 0 fills the Thousands, Hundreds, and Tens places, showing no value in these places.
• The digit 4 is in the Ones place, representing 4.

(c) 3,58,309:

• The digit 3 is in the Lakhs place, representing 3,00,000.
• The digit 5 is in the Ten Thousands place, representing 50,000.
• The digit 8 is in the Thousands place, representing 8,000.
• The digit 3 is in the Hundreds place, representing 300.
• 0 is in the Tens place, showing no value here.
• The digit 9 is in the Ones place, representing 9.

By placing each digit in the correct place-value column, we can understand the full value of each number.

Sol: (a) 8,00,000 + 2,000 + 30 + 6 = 8,02,036
We start by adding the place values together:

• 8,00,000 (Lakhs place)
• 2,000 (Thousands place)
• 30 (Tens place)
• 6 (Ones place)
• When we put these values together in one number, we get 8,02,036.
  

(b) 9,00,000 + 4,000 + 200 = 9,04,200

We add the place values:

• 9,00,000 (Lakhs place)
• 4,000 (Thousands place)
• 200 (Hundreds place)
• Writing these together as one number gives 9,04,200.
  

(c) 5,000 + 300 + 40 + 3 = 5,343

We add each place value:

• 5,000 (Thousands place)
• 300 (Hundreds place)
• 40 (Tens place)
• 3 (Ones place)
• Combining these values results in the short form 5,343.

Sol: Comparing two numbers involves determining their relationship in terms of magnitude. Here's how you can interpret the symbols ">" (greater than), "<" (less than), and "=" (equal to):

• List the Numbers: Write down all the numbers you want to arrange.
• Identify the Largest Number: Find the largest number in the list. This will be the first number in your descending order arrangement.
• Write the Largest Number: Write down the largest number at the top.
• Remove the Largest Number: Once you've written down the largest number, remove it from the original list.
• Repeat the Process: Continue the process by identifying the next largest number from the remaining list and writing it down below the first number.
• Continue Until All Numbers are Listed: Repeat these steps until you have listed all the numbers in descending order.(a) 6,53,192; 6,35,294; 1,28,193; 68,156; 6,346
  (b)  7,19,076; 4,54,839; 2,81,263; 2,35,245; 81,526

The number 3,69,510 is greater because, at the tens place, 510 is greater than 501.

In the number 7,52,693, the 2 is in the thousands place, so its place value is 2,000.
