Question 86643: I had to create a rational expression. I created 120+10(9)/9 based on a real life situation. My teacher said I did great, however he is asking me too try the expression in a different way which would give me a different answer. He gave me this: [120+10(9)]/9 How would the answer be different from the one I got when I solved it the other way?
My original answer for my expression was 23.3, the answer I get with my teachers way is 130? Which way is the right way?
