Hi namokshi,

From your post, I'm going to assume that the equation that you included is meant to be:

Z = 1 + (1/X) and X > 1

As X increases, the value of (1/X) decreases - so we'll be adding a potentially small fraction to 1. We can actually TEST THE ANSWERS here - and use the answer choices to our advantage (by considering the DENOMINATORS of each of the 5 answers). If X = 7, then we'd end up with Z = 1 + (1/7) = 8/7

Final Answer: E

 If z=1+1/x where x>1, then z could equal to which of the following?
a. 1/5
b. 5/8
c. 9/7
d. 15.11
e. 8/7
Just in case you need you homework help and it happens that you wait for the answer real long time here, you can ask for help form experts on homework help sites.
