x=6.429

#### Work Step by Step

To solve for x in the equation $\frac{7}{5}$=$\frac{9}{x}$ we'll first cross multiply which will result in (7)(x)=(9)(5) 7x=45 Then, to solve for x, we'll divide by 7 on both sides of the equation, so $\frac{7x}{7}$=$\frac{45}{7}$, and x=$\frac{45}{7}$, which, rounded to the nearest thousandth, is 6.429
