Answer:
Option A is correct option
Step-by-step explanation:
We need to find which number sentence is not true.
We will check each option.
Option A
|-20| < 20
We know that |-a|=a
20 < 20 (false)
So, this number sentence is not true.
Option B
|9| = 9
We know that |a|=a
9=9 (true)
So, this number sentence is true.
Option C
|-20|>|9|
We know that |-a|=a
20>9 (true)
So, this number sentence is true.
Option D
|9| < 20
We know that |a|=a
9<20
So, this number sentence is true.
So, Option A is correct option
