Place Value Relationships
In the number 330, what is the relationship between the value of
the digit 3 in each place?
330
300
The first 3 is in the hundreds place.
Its value is 300.
30
The second 3 is in the tens place.
Its value is 30.
Since 300 is ten times as great as 30, the first 3 is worth 10 times
as much as the second 3. When two digits next to each other in
a number are the same, the one on the left is always 10 times as
great as the one on the right.
Name the values of the given digits in the numbers below.
1. the 4s in 440
400; 40
2. the 8s in 8,800
8,000; 800

number in the ones place does not change the placevalue relationship between the 6s in the hundreds
and tens places.
