What is 6.65 rounded to the nearest tenth?

Answer 1

6.7

Answer 2

When rounding a number to the nearest tenth, you look at the digit in the hundredths place. In this case, the digit in the hundredths place is 5, which is equal to or greater than 5. Therefore, you round the number up to the next whole number in the tenths place. So, 6.65 rounded to the nearest tenth is 6.7.

Answer 3

It is 6.6

Most schools teach you to always round 5 up (to 6.7). However, doing so is inappropriate because it introduces an upward bias. The IEEE (Institute of Electronic and Electrical Engineers) standard 754 is to round 5 up or down so that the new last digit is even.
