Julie made a scale drawing of a hotel. a room in the hotel, which is 12 feet wide in real life, is 2 inches wide in the drawing. what scale did julie use?

I think it is

1: 72

because there are 12 inches in a foot, and the room is 12 feet wide. 12 feet is 144 inches ( 12 x 12), and in the drawing, the width is 2 inches.

So, it went from its original 144 inches to 2 inches. I think it can also be written as 1: 72 because 1 is it's original from, and it became 72 times smaller.
