Answer 1

You have to use a process called &quot;factor labeling&quot; or &quot;dimensional analysis&quot;

1) 3 km x (1000 meters/1km)= 3000 meters

So work your way to the answer you&#039;re looking for. When you multiply, you have to cancel the unit(s) you don&#039;t need.

EX: How many feet is 2 miles?

(2 mi/1) x (5280 ft/1 mi)

Here&#039;s No. 2:

2 m x (100 cm/1 m)= 200 cm

Have fun working those problems out.
