Rounding - practice problems
Rounding is the process of approximating a number to a specified degree of precision by replacing it with a nearby simpler value. The most common method rounds to the nearest place value: if the digit to the right is 5 or greater, round up; otherwise, round down. Rounding can be done to various place values including ones, tens, hundreds, or decimal places. Special cases include rounding to significant figures, which considers the precision of measurements. This technique is essential for estimation, simplifying calculations, and presenting data appropriately. Understanding when and how to round is crucial in science, finance, statistics, and everyday numerical reasoning.Number of problems found: 556
