Answer 2

3.470

Explanation:

The given number is 3.46964490715

We need to round 3 decimal places.

The third decimal place is 9.

To round off we have to look for the next right digit. Which is 6.

If it is greater than or equal to 5, we can add 1 with third decimal place digit. if it is less than 5, we can keep the digit as it is.

But we have 6, which is greater than 5. So add 1 with the third decimal place digit.

9 + 1 = 10

Since it is 10, we place 0 in the third decimal place and carry over 1 with the second decimal place.

So, we get 3.470.

The answer is 3.470
