Work Step by Step
Factor each term then eliminate any factors that are common to numerators and denominators.
If all factors are eliminated, the result is 1.
$\frac{7}{x}\times\frac{5x}{35}=\frac{\big/\!\!\!7}{\big/\!\!\!x}\times\frac{\big/\!\!\!5\times\big/\!\!\!x}{\big/\!\!\!7\times\big/\!\!5}=1$
