$\sf{Let \: the \: required \: no. \: be \: x. }$

$\sf{A/Q, }$

$\implies \: \sf \frac{9 + x}{17 + x} = \frac{5}{7}$

$\implies \: \sf{7(9 + x) = 5(17 + x)}$

$\implies \: \sf{63+ 7x = 85 + 5x}$

$\implies \: \sf{2x = \: 22 }$

$\implies \: \sf{x = 11}$

$\sf{ \red{Hence \: our \: \: required \: number \: is \: 11}}</p><p>$
