Sample Problem

Round the following decimal to 3 decimal places (thousandths).

0.1674 ≈

Solution

When rounding the decimals to the nearest thousandths place, to decide whether to round up or stay the same, look at the number to the right of the thousandths place.

If the number is 5 or greater, round the thousandths place up and drop the digits after the thousandths place;

If the number is smaller than 5, keep the same thousandths place and drop the digits after the thousandths place.

Look at the number to the right of the thousandths place.

4 is less than 5

So 0.1674 ≈ 0.167
