Question

What is the difference?

9/5 - 1/6



My answer is 49/30

Answer 1

You are correct. I got the same answer as you when I did the problem, so it has to be 49/30 as the answer.

Answer 2

First, you would find the LCD - least common denominator- of 5 and 6, which is basically a number that the both of them can go into. In this case, it is 30. Then you would mulitply 9/5 * 6/6 for 54/30 and 1/6 * 5/5 for 5/30. Now your new expression reads 54/30 - 5/30, which is.... your amswer. Simplify.
