What is 3905 rounded to the nearest ten?

Answer 1

3900

Answer 2

It is 3900.

Although many schools teach you to round 5 up, always rounding up from 5 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.

Answer 3

To round 3905 to the nearest ten, you would look at the digit in the tens place, which is 0. Since 0 is less than 5, you would round down. Therefore, 3905 rounded to the nearest ten is 3910.

Answer 4

3910
