Problem 1 :
Compare |-7| and |-9|
Problem 2 :
Compare |-4| and |-4|
Problem 3 :
Compare |3| and |9|
Problem 4 :
Compare |-15| and |1|
Problem 5 :
Compare |-6| and |-4|
1. Answer :
Compare |-7| and |-9| :
Step 1 :
The absolute value of a number is the number’s distance from 0 on a number line.
To understand this, let us mark -7 and -9 on a number line.
Step 2 :
On the above number line, -7 is 7 units from 0.
Since -7 is 7 units from 0, we say that the absolute value of -7 is 7.
The absolute value of -7 is written |-7|.
And, we have
|-7| = 7 ----(1)
Step 3 :
On the above number line, - 9 is 9 units from 0.
Since -9 is 9 units from 0, we say that the absolute value of -9 is 9.
The absolute value of -9 is written |-9|.
And we have
|-9| = 9 ----(2)
Step 4 :
From (1) and (2), it is clear that 9 is greater than 7.
So, |-9| is greater than |-7|.
2. Answer :
Compare |-4| and |-4| :
Step 1 :
The absolute value of a number is the number’s distance from 0 on a number line.
To understand this, let us mark -4 and 4 on a number line.
Step 2 :
On the above number line, -4 is 4 units from 0 to the left.
Since -4 is 4 units from 0, we say that the absolute value of -4 is 7.
The absolute value of -4 is written |-4|.
And we have
|-4| = 4 ----(1)
Step 3 :
On the above number line, 4 is 4 units from 0 to the right.
Since 4 is 4 units from 0, we say that the absolute value of 4 is 4.
The absolute value of 4 is written |4|.
And |4| = 4 ----(2)
Step 4 :
From (1) and (2), it is clear that 4 is equal to 4.
So, |-4| is equal to |4|.
3. Answer :
Compare |3| and |9| :
As we have solved the above two problems, we can solve this one and get the following answer.
|9| is greater than |3|
4. Answer :
Compare |-15| and |1| :
|-15| is greater than |1|
5. Answer :
Compare |-6| and |-4| :
|-6| is greater than |-4|
