Question

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

Answer 1

i think the answer is 0.40

Answer 2

Option 2 -
`√(15)-√(12)=0.4`

Explanation:

Given : Number line plotted
`√(12)` and
`√(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
`√(12)` and
`√(15)`

Count the scale between the numbers
`√(12)` and
`√(15)`

is 4.

Now, 4 scale = 0.1 × 4=0.4.

Therefore, The difference between the number is

`√(15)-√(12)=0.4`

So, Option 2 is correct.
