6,300 and 530
The value of 3 in _____ is _____ times the value of 3 in _____.

Answer: The value of 3 in 6,300 is 10 times the value of 3 in 530.

Explanation:
Every digit in a number has a place value and the place value can be defined as the value represented by a digit in a number on the basis of its position in the number. So the place value of the digit 3 in 6,300 is 300. And the place value of the digit 3 in 530 is 30. As each hundred is 10 times as many as 10, so 3 hundreds are ten times as many as 3 tens. So, the value of 3 in 6,300 is 10 times the value of 3 in 530.

Question 10.
2,783 and 7,283

Explanation:
Every digit in a number has a place value and the place value can be defined as the value represented by a digit in a number on the basis of its position in the number. So the place value of the digit 2 in 2,783 is 2000. And the place value of the digit 2 in 7,283 is 200. As each hundred is 10 times as many as 10, so 2 thousands are ten times as many as 2 hundred. So, the value of 2 in 2783 is 10 times the value of 2 in 7283.

Question 11.

Explanation:
Every digit in a number has a place value and the place value can be defined as the value represented by a digit in a number on the basis of its position in the number. So the place value of the digit 4 in 34,258 is 4,000. And the place value of the digit 4 in 47,163 is 40,000. As each hundred is 10 times as many as 10, so 4 thousands are ten times as many as 4 thousand tens. So, the value of 4 in 47,163 is 10 times the value of 4 in 34,258.

Question 12.
503,497 and 26,475
The value of 7 in _____ is _____ times the value of 7 in _____.

Answer: The value of 7 in 26,475 is 10 times the value of 7 in 5,03,497.

Explanation:
Every digit in a number has a place value and the place value can be defined as the value represented by a digit in a number on the basis of its position in the number. So the place value of the digit 7 in 503,497 is 7. And the place value of the digit 7 in 26,475 is 70. As each hundred is 10 times as many as 10, so 7 are ten times as many as 7 tens. So, the value of 7 in 26,475 is 10 times the value of 7 in 5,03,497.

Question 13.
What is the value of the digit 9 in the attendance at the Redskins vs. Titans game?

Question 14.
The attendance at which game has a 7 in the ten thousands place?
__________

Explanation:
Each digit of the number holds its own value. The adjacent digits of the number differ from each other by 10 times. Starting from the leftmost digit going to the right, the order of place values starts from ones, tens, hundreds, thousands, and ten thousand. Therefore, the number should contain a digit 7 on the 5th digit from left to right.
Thus the attendance at Ravens vs. Panthers game has a 7 in the ten thousands place.

Question 15.
How does a digit in the ten thousands place compare to a digit in the thousands place?
Type below:
__________

A digit in the ten thousand place has a value of 10,000 times the value of the mere digit. While a digit in the thousands place has a value 1,000 times the value of the digit. So to compare you can do 10,000 / 1,000 = 10, which means that a digit in the ten thousand place values ten times what the same digit values are it is the thousand place.
