When a number ends in a zero, it's easy to express that number in terms of tens.
For example, let's consider the following number:
Notice that this number ends in a zero. Therefore, we can write it as a multiple of as follows:
Therefore, is the same as " tens."
In the future, we'll see how this method can be used to solve problems involving multiplication and division easily.
Write in terms of tens.
We know that
Therefore, is the same as tens.
$560$ is the same as
|
a
|
$560$ hundreds |
|
b
|
$56$ tens |
|
c
|
$56$ thousands |
|
d
|
$56$ ones |
|
e
|
$560$ tens |
$7,920$ is the same as
|
a
|
$7,920$ tens |
|
b
|
$792$ tens |
|
c
|
$792$ hundreds |
|
d
|
$79,200$ tens |
|
e
|
$7,920$ hundreds |
When a number ends in two zeros, we can easily express it in terms of hundreds.
For example, let's consider the following number:
Notice that this number ends in two zeros. Therefore, we can write it as a multiple of as follows:
Therefore, is the same as " hundreds."
Similarly, when a number ends in three zeros, it's easy to express it in terms of thousands. Let's see an example.
What is in terms of thousands?
We know that
Therefore, is the same as thousands.
$3,600$ is the same as
|
a
|
$3,600$ hundreds |
|
b
|
$360$ ones |
|
c
|
$36$ hundreds |
|
d
|
$36$ tens |
|
e
|
$360$ hundreds |
$72,000$ is the same as
|
a
|
$720$ thousands |
|
b
|
$72$ hundreds |
|
c
|
$72$ tens |
|
d
|
$72$ thousands |
|
e
|
$720$ tens |
