Rounding to the nearest whole number

In many calculations you will be expected to round off your answer to the nearest whole number or to the nearest ten.

Write \(38.7\) to the nearest whole number

\(38.7\) lies between \(38\) and \(39\)

\(38.7\) is nearer to \(39\) than \(38\)

So, \(38.7 = 39\) (to the nearest whole number)

Write \(6.5\) to the nearest whole number

\(6.5\) lies between \(6\) and \(7\)

\(6.5\) lies mid-way between \(6\) and \(7\)

When this happens always round up

So, \(6.5 = 7\) (to the nearest whole number)

Now try this question:
