Thread: Fraction Conundrum

How to solve this Question?
:

1/z+ 1/y+ 1/x + 1/w + 1/v + 1/t + 1/s = 1

1/z means 1 over z a fraction.
The letters can be any number.
How to find seven numbers that fit into the equation?

(the numerator is always 1)

What if its 8 sets or 9 sets of fraction? is there any technique?

In my opinion the letters can be just about any numbers, unless there is something special about them. Such as a ratio between them. Is this actually a real problem or did you make it up?

janvdl is right, in this specific case you have only one constraint and seven unknowns which means that you have 6 D.O.F.'s --> you can choose six of the variables to be whatever you want and the last variable is determined by the equation at hand.

How about
s = t = v = w = x = y = z = 7?

Hello, hotgal24!

What is the exact wording of the problem?

Solve: .

The letters can be any number. . . . . Really?

Then we can have: . . . . duh!


Or how about:

. .

I would assume the denominators must be distinct positive integers.
. . If so, I have a solution for it.

The different letters must be different positive integer number lowest possible.
