How do you round 1.89 to the nearest tenth?

Answer 1

The tenths, on either side of 1.89 are

1.8 which is at a distance of 1.89 - 1.8 = 0.09,

and

1.9 which is at a distance of 1.9 - 1.89 = 0.01.

The second is the nearest, so the answer is 1.9

Answer 2

1.89 rounded to the nearest tenth is 1.9. Any time the digit to the right of the place you are rounding to is 5 or more, you round up one number. Otherwise, the number in the place you are rounding to does not change.

Answer 3
