What is 9/11=?/22 if it was a whole number?

Answer 1

$?=x\\\\\frac{9}{11}=\frac{x}{22}\ \ \ |it's\ a\ proportion\ \ \ |cross\ multiply\\\\11\cdot x=9\cdot22\ \ \ \ |divide\ both\ sides\ by\ 11\\\\x=\frac{9\cdot\not22^2}{\not11_1}\\\\x=\frac{9\cdot2}{1}\\\\\boxed{x=18}$

Answer 2

The question mark will be 18 as
the denominator x 2 (11 x 2 = 22) so 9 x 2 = 18
