Question

What is the approximate difference in tenths between √12 and √15?

Answer 1

Answer:

Option 2 -  $\sqrt{15}-\sqrt{12}=0.4$                            

Step-by-step explanation:

Given : Number line plotted $\sqrt{12}$ and $\sqrt{15}$

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 $\sqrt{12}$ and $\sqrt{15}$

Count the scale between the numbers $\sqrt{12}$ and $\sqrt{15}$

is 4.

Now, 4 scale = 0.1 × 4=0.4.

Therefore, The difference between the number is

$\sqrt{15}-\sqrt{12}=0.4$

So, Option 2 is correct.

Answer 2

I think the answer is 0.40
