Question

Both quantities in a ratio have the same units . That means you can do what to the units ?

Answer 1

cancel them out

Explanation:

You can eliminate them since they cancel out.

In a ratio, you compare numbers by dividing them.

For example, if the ratio is 4 cm to 5 cm, then you can write

`(4~cm)/(5~cm)`

Now divide the numerator and denominator by cm.

You get:

`(4)/(5)`

As you can see, the same units cancel out.
