Answer 2

Step-by-step explanation:

1) √90 ≈ 9.5

2) √150 ≈ 12.2

3) √600 ≈ 24.5

Step-by-step explanation:

We know that

√90 ≈ 9.4868

To approximate 9.4868 to one decimal place we have to look on second digit after point.

"If it is greater then 5 then we will add 1 in first digit after point."

In our case it is 8 which is greater then 5 so we add 1 in 4 to get 5

And

√90 ≈ 9.5

Now

√150 ≈ 12.2474

Here second digit after point is 4 which is less then 5 so we will not add 1

And so

√150 ≈ 12.2

Now

√600 ≈ 24.4948

Here second digit after point is 9 which is greater then 5.So we add 1 in 4 to get 5.

And

√600 ≈ 24.5
