# Question #29219

##### 1 Answer

Here's how you can do that.

#### Explanation:

In order to round your number off to two significant figures, you must compare the value of the **third significant digit** to

If the third significant digit is **add** **second significant digit** and eliminate everything that follows this digit. If the third significant digit is **unchanged** and eliminate everything that follows this digit.

In your case, you have

#color(red)(color(black)(4.)4color(blue)(4)color(black)(5))#

Here

#color(red)(4) -># thesecond significant digit#color(blue)(4) -># thethird significant digit

When you compare the third significant digit to

#color(blue)(4) < 5#

This means that you must leave the second significant digit **unchanged** and eliminate everything that follows this digit.

#4.4color(red)(cancel(color(black)(45)))#

You will thus have

#4.445 ~~ 4.4 -># rounded totwo sig figs
