#### Answer:

#### Explanation:

To convert **conversion factor**. A **conversion factor** is a ratio expressed as a fraction **equal to 1**. We multiply the conversion factor by a measurement which allows us to change the units while keeping the original measurements the same.

Examples of common conversion factors:

#1# day#=24# hours#1# minute#=60# seconds#1# dozen#=12# things

#(1m)/(100cm)#

#1800cm*(1m)/(100cm)#

#=1800color(red)cancelcolor(black)(cm)*(1m)/(100color(red)cancelcolor(black)(cm))#

#=(1800m)/100#

#=color(green)(|bar(ul(color(white)(a/a)18mcolor(white)(a/a)|)))#
