Estimating numbers using rounding

This module shows you how to work out equivalent fractions followed by a number of exercises to practice.

Rounding can be used as a quick way of getting a rough idea or estimate of a number. It may be a little less or a little more.

There may be times when you need to provide a number that does not need to be exact. Rounding makes it easier and faster, and its near enough is still useful.
