Question

4 out of every 5 vehicles at a car dealership have a sticker price greater than 25,000. What fraction of vehicles at the dealership cost less than 25,000?

Answer 1

I just have to complain about the wording of your teacher's question.

 

The expression not greater than does not mean the same as less than.   

 

For example.....10 is greater than 7.

                         5 is not greater than 7

                         7 is not greater than 7.

 

So not greater than means less than OR equal to.....so technically, you can't answer your question!!!

 

But if 4 out of 5 cars is greater than 25000, then the other 1 out of the 5 is not greater than 25000....so your fraction should be 1/5 of the cars is not greater than 25000.
