Class V Mathematics worksheet focusing on place value concepts with fill-in-the-blanks exercises.

Here are the solutions to the worksheet problems, worked out step by step.

1) A 7-digit number begins at the \_\_\_\_\_\_ place.
* Reasoning: Let's count the places from right to left: Ones, Tens, Hundreds, Thousands, Ten Thousands, Lakhs, Ten Lakhs. The 7th digit is in the Ten Lakhs place.
* Answer: Ten lakhs

2) An 8-digit number begins at the \_\_\_\_\_\_ place.
* Reasoning: Continuing from above, the next place after Ten Lakhs is Crores. So, an 8-digit number starts with Crores.
* Answer: Crores

3) 1 crore = \_\_\_\_\_\_ lakhs
* Reasoning: In the Indian numbering system, 100 lakhs make 1 crore.
* Answer: 100

4) The number with more digits is the \_\_\_\_\_\_ number.
* Reasoning: When comparing whole numbers, the one that has more digits is always larger (for example, a 3-digit number like 100 is bigger than any 2-digit number like 99).
* Answer: greater (or larger)

5) There are \_\_\_\_\_\_ two digit numbers.
* Reasoning: Two-digit numbers start at 10 and end at 99. To find the count: $99 - 10 + 1 = 90$.
* Answer: 90

6) There are \_\_\_\_\_\_ three digit numbers.
* Reasoning: Three-digit numbers start at 100 and end at 999. To find the count: $999 - 100 + 1 = 900$.
* Answer: 900

7) There are \_\_\_\_\_\_ four digit numbers.
* Reasoning: Four-digit numbers start at 1000 and end at 9999. To find the count: $9999 - 1000 + 1 = 9000$.
* Answer: 9000

8) The place value of 6 in 4,36,728 is \_\_\_\_\_\_.
* Reasoning: Looking at the number 4,36,728:
* 8 is in the Ones place.
* 2 is in the Tens place.
* 7 is in the Hundreds place.
* 6 is in the Thousands place.
* Therefore, its value is $6 \times 1,000$.
* Answer: 6,000

9) The international system has \_\_\_\_\_\_ places in each period.
* Reasoning: In the International system, commas are placed after every 3 digits (e.g., 1,000,000). This means each period (ones, thousands, millions) consists of 3 places.
* Answer: 3

10) In Indian system and international system the only period which has same number of places is \_\_\_\_\_\_.
* Reasoning: Both systems group the first three digits (Ones, Tens, Hundreds) together before the first comma. After that, the Indian system groups by 2s (Thousands, Lakhs) and the International system groups by 3s (Thousands, Millions). So, only the "Ones" period is the same.
* Answer: Ones

11) 1 million = \_\_\_\_\_\_ lakhs.
* Reasoning: 1 million is written as 1,000,000. In the Indian system, this is written as 10,00,000, which is read as 10 lakhs.
* Answer: 10

12) One crore = \_\_\_\_\_\_ lakhs.
* Reasoning: This is the same as question #3. 1 crore is equal to 100 lakhs.
* Answer: 100

13) When we round a number to the nearest 10, we use the nearest \_\_\_\_\_\_.
* Reasoning: To round to the nearest 10, you look at the digit in the ones place. If it is 5 or more, you round up; if it is less than 5, you round down. You are essentially finding the closest multiple of 10.
* Answer: multiple of 10

14) When we round a number to the nearest 1000, we use the nearest \_\_\_\_\_\_.
* Reasoning: Similar to the previous question, when rounding to the nearest 1000, you look for the closest multiple of 1000.
* Answer: multiple of 1000
