Answer:
Option 2 - [tex]\sqrt{15}-\sqrt{12}=0.4[/tex]
Step-by-step explanation:
Given : Number line plotted [tex]\sqrt{12}[/tex] and [tex]\sqrt{15}[/tex]
To find : What is the approximate difference in tenths between the numbers?
Solution :
In a number line 1 unit i.e. from 0 to 1 is divided into 10 parts.
So, 1 scale = 0.1 unit.
We have to find the difference between [tex]\sqrt{12}[/tex] and [tex]\sqrt{15}[/tex]
Count the scale between the numbers [tex]\sqrt{12}[/tex] and [tex]\sqrt{15}[/tex]
is 4.
Now, 4 scale = 0.1 × 4=0.4.
Therefore, The difference between the number is
[tex]\sqrt{15}-\sqrt{12}=0.4[/tex]
So, Option 2 is correct.
