If 72° is used ti represent 4 people. How many people were there altogether?

Is there any possibility that you're looking at a pie-chart and not

sharing it with us?

Let's see. If 72° represent 4 people, then each person is (72°/4) = 18°.

But then they would all freeze and get sick. No, that can't be it. It must

be the other kind of degrees ... the kind in circles and angles.

OK. If 72° represent 4 people, then each person is (72°/4) = 18°.

Now, if the whole crowd exactly fits into one full circle, how many

could that be?

Well, there are always 360° in one full circle. And each person

uses 18°. So how many times can 18° fit into a full circle?

(360°) / (18°) = 20 times.

So 20 people exactly fit into one whole circle.

Does the question have anything to do with that?
