thanksHello, and welcome to FMH!

It appear the output is \(\displaystyle \frac{3}{44}\) of the input, of:

\(\displaystyle f(x)=\frac{3}{44}x\)

Hence:

\(\displaystyle f(12)=\frac{3}{44}\cdot12=\frac{9}{11}\)

Another way to get at it:

if 11 goes to 0.75 (11 : 0.75)

and 22 goes to 1.5 (22 : 1.5)

what would 12 go to?? (12 : ?)

11/(0.75) = 12/x .......................................(here : is like division)

x = 12* 0.75/11 = 9/11
