The 7th grade contributed $60 towards refreshments and the 6th grade contributed $50. How much money did the 7th grade contribute for each dollar the 6th grade contributed?

You essentially have a fraction of 60/50. You can simplify it to 6/5, making six dollars for every five dollars. 6/5 equals 1.20, therefore

the 7th grade contributed $1,20 per $1.00 contributed by the 6th grade.
