Rounding a measurement results in a less accurate measurement and introduces a certain quantity of error. When dealing with rounded measurements, we have to keep in mind the following aspects:   Look at the value immediately to the right of the position that has to be rounded.   If the value is 5 or greater, the place value should be rounded up by 1. Otherwise, we don’t change the place value.   For example, Rounding to the nearest tenths, 11.35 becomes 11.4. Rounding to the nearest tenths, 7.339 becomes 7.3.
