# How do you round 65.145 meters to three significant figures?

Aug 26, 2016

$65.1$

#### Explanation:

The number

${\underbrace{65.145}}_{5 \text{ significant figures}}$

could be rounded to three significant figures as:

${\underbrace{65.1}}_{3 \text{ significant figures}}$

Note that it is $65.1$ and not $65.2$ because the number next to $.1$ is $4$ which is smaller than $5$.

However, if the number was for example $65.155$ it could be then rounded to $65.2$.
