p6fitz: The scale model of a 72-inch long table is 8 inches long.
It is just 8:72
You do have to be a little careful, the units have to be the same in the first place.
Here they are both inches so that is fine.
now you can just simplify the same as you would simplify a fraction.
That is, you can divide both sides by 8 to get the most simple ratio.
