The words go on top.

2 Divide to get 1 at the bottom

We want 1 minute on the bottom.

4 divided by 4 is 1.

We divide the top by 4 too, so the rate stays the same.

= 240 words ÷ 44 minutes ÷ 4

240 divided by 4 is 60.

So it is 60 words for 1 minute.

Per means for each.

So the unit rate is 60 words per minute.
