Most math teachers will prefer 7/2 rather than 3 1/2. Of course, both are correct and work. In terms of practicality however, it is easier to work around with multiplication, inverses, and division when the fraction is in improper form.

yes, you need to use 7/2 in this form because you use the numerator to find out up/down and the denominator tells you how far across.
