Rounding to a given number of places

Decimal places are counted from the decimal point:

So, the number \(5.1492\) has four decimal places, while \(4.34\) has two decimal places.

Round \(9.6371\) to \(2\) decimal places

This means we need \(2\) digits after the decimal point.

Because the next digit \(7\), is more than \(5\), we round the \(3\) up.

\(9.6371 = 9.64\) (\(2\) decimal places)

Question

Q1. Round \(7.2648\) to \(2\) decimal places.

Q2. Round \(8.352\) to \(1\) decimal place.

For example, rounding \(3.40021\) to two decimal places gives \(3.40\).

You need to write both decimal places, even though the second number is a zero, to show that you rounded to two decimal places.

Remember to look at the number after the one you're interested in. If it's less than \(5\), round down. If it's \(5\) or more, round up.
