How do you round off number 1.875 to the nearest whole number?

Answer 1

When needing to round, always look to the number exactly to the right of the place value you wish to round.

In our case we have ones, tenths, hundredths, and thousandths. One is the whole number in our problem and the number we're going to be rounding to. So we need to look at the place value to the right which is our tenths.

The rules of rounding are pretty straightforward. If the place value to the right of the number you want to round to is 5 or more you round up. (1.5 goes to 2. 2.8 goes to 3.0) If the place value is 4 or less you round down. (1.4 goes to 1, 2.3 goes to 2.0).

1.8 since the 8, which is the place value to the right of the number we want to round, is greater than 5 we round up. 1.8 becomes 2.0.

So 1.875 rounded to the nearest whole number is 2.0. (We removed the insignificant digits.)
