How can I round 57.62811813689564 to the nearest tenth? Answer back fast please?

Question

Hi can you please tell me how to do this and how because I'm having trouble, thanks!

Answer 1

To round a number to the nearest tenth, you look at the digit in the hundredths place.

For the number 57.62811813689564, the digit in the tenths place is 6 and the digit in the hundredths place is 2.

If the digit in the hundredths place is less than 5, we keep the digit in the tenths place as it is and drop all the digits after the tenths place.

Since 2 is less than 5, when we round 57.62811813689564 to the nearest tenth, the result is 57.6.

So the answer is 57.6.

Answer 2

The tenth place is always the FIRST number (position) after the decimal.  So most of this problem will just disappear.  In the tenth place, you currently have a 6.  You look one place to the right, to decide whether to keep that at a 6, or round up to a 7.  Those are your two choices.  Looking right, I see a 2 in the hundredths place, which means DON'T round up.  (You only round up if that digit to the right of where you want to round to, is 5 or higher.)  Your final answer includes everything to the LEFT, but stops at that tenth place, so it would be 57.6
