How do you find a square root to the nearest tenth?

Answer 1

-- Calculate the square root in the usual fashion, continuing until you have

two digits after the decimal point.

-- If the second digit after the point is 4 or less, discard it, and what's left

is your answer.

-- If the second digit after the point is 5 or more, discard it, and increase the

first digit after the point by '1' to get your answer.
