To find alternative ratios, you can divide both sides by a common factor (this will simplify it) or multiply them both by the same factor.

So, for $12:9$ , we can divide both sides by $3$ :

$12/3:9/3 = 4:3$

Or we can multiply both sides by any number, as long as it is the same for both:

e.g. by $2$

$12xx2:9xx2 = 24:18$

e.g. by $1 1/3$

$12xx 1 1/3: 9 xx 1 1/3 = 16:12$

So, three equivalent ratios (of the many possibilities) are:

$4:3$
$24:18$
$16:12$

Hope this helps; let me know if I can do anything else.
