Round 0.681 to the nearest tenth.

0.7

To round a number to the nearest tenth, you need to look at the digit in the hundredths place, which is the third decimal place. In this case, the digit in the hundredths place is 1.

Since 1 is less than 5, you can round down.

To round down, simply drop all the digits after the tenths place, so the answer would be 0.7 when rounded to the nearest tenth.
