This is from Ten Real SATs. Its the 1997 test.
If y=1 + (1/x)
and x>1 then Y could equal...
The answer is 9/7
Does anyone know why?

since x > 1 then 1/x has to be < 1
so the answer has to be between 1 and 2

Hmm...are you sure it's 9/7? Because y = 1 + (1/x) = (x + 1)/x
So the numerator would seemingly have to be one more than the denominator...which isn't exactly satisfied with 9/7...

I mean...technically, x COULD equal 3.5, which would make (x + 1)/x = 9/7. But...this question is a little odd. Was this a multiple choice question?

You're going to have to type up the FULL question, because as it is the answer could anywhere between 1 and 2.

ya its multiple choice...hmm i see how that is now. I would expect X to be a whole number.
The other choices are
Oh and its from the Sunday May 1996 test
Its section 1 and its number 17

9/7 is the only solution between 1 and 2

Kevinkleinz, 9/7 is a fraction where the numerator is not one greater than the denominator, but 4.5/3.5 is, and they are equal.
