Amodel of a famous statue is 2 and one half inches tall. the actual statue is 6 and two thirds feet tall. what is the ratio of the height of the model to the height of the actual statue in simplest form?

First, you will need to find a common denominator and turn it into a ratio.
1 2/4 : 5 1/4
Then you will need to turn it into an improper fraction.
6/4 : 21/4
You can then divide the numerators by 3 and then simplify from there.
1/2 : 1 3/4 
I hope this helps :)
