​

Answer 1

$\Huge{\underline{\underline{\mathfrak{ Solution }}}}}$

$\sf {Let\ the\ radii\ be\ 5x\ and\ 3x.}\\\\\sf {Circumference\ of\ first\ circle\ = 2\pi (5x)}\\\sf {Circumference\ of\ the\ second\ circle\ =2\pi (3x)}\\\\\sf {Ratio\ =\frac{ 2\pi (5x) }{2 pi (3x)} = \frac{5}{3}}\\\\\sf {= 5:3}$
