This document discusses rounding numbers and provides examples. It explains that rounding is used to get an estimate rather than an exact amount, and the rounded number will typically end in one or more zeros. When rounding a mixed number to the nearest whole number, if the fractional part is less than half, round down, and if it is greater than half, round up. Several examples of rounding numbers are then provided.

Lesson 17:
*We round numbers to get an estimate, rather than an exact
amount.
*Typically that number will end in 1 or more zeros!
*To round a mixed number to the nearest whole number, we decide
if the fraction is more than or less than 1/2.
<1/2... round down
>1/2... round up
