We have,

$x:15=63:45$

As we can see that the given numbers are in proportion.

so we can write the above number in the form of a ratio.

That is

$\frac{x}{15} =\frac{63}{45}$

Solving the above equation further we get,

$=>45\times x=63\times15\\=>45x=945\\\\=>x=\frac{945}{45} \\\\=>x=21$

Hence, the value of $x$is$21$.
