Assume a value for x and y which satisfies the values in the number line
Using x = \(\frac{1}{5}\) and y =\(\frac{1}{2}\), let's evaluate the answer options.
A. \(x > y\) -> \(0.2 > 0.5\) (Not true)
B. \(\frac{1}{x} < \frac{1}{y}\) -> \(5 < 2\) (Not true)
C. \(\frac{1}{x}*\frac{1}{y} > 9\) -> \(4*2 > 9\) (Not true)
D. \(xy < \frac{1}{3}\) -> \(1/8 < 1/3\) (True)
E. \(x+y > 1\) -> \(0.2 + 0.5 > 1\) (Not true)
By the process of elimination, Option D(\(xy < \frac{1}{3}\)) is the correct answer option.
