To round to the nearest tenth of a percent, a person must reduce two or more decimal points to one decimal point. For instance, a percentage of 82.34 is rounded to 82.3 percent, because 82.34 is closer to 82.3 than 82.4.
Rounding to the nearest tenth of a percent is a way to simplify a statistical recording of a percentage. In grading, for instance, teachers may round for simple recordkeeping. If a student achieves an 82.34 percent, a teacher may round to 82.3 percent or even eliminate the tenth and round to 82 percent. A calculator often shows this percent as 0.8234, which represents 82.34 percent.
