Step-by-step explanation:
In this case we must compare 2 to 4 and 11 to 11/2
1. The first ratio given is 2 to 4
![r_1=(2)/(4)=(1)/(2)](https://img.qammunity.org/2023/formulas/mathematics/college/aiw6n72a3eyd3w25pvvqey6ztjtcbut5ay.png)
So, the first ratio is 1/2
2. The second ratio given is 11 to 11/2
![\begin{gathered} r_2=(11)/((11)/(2))=(2\cdot11)/(11) \\ r_2=2 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/8t4zsui61uvdexkced6ue6c3fsallnsgts.png)
Finally, since r1 ≠ r2 they are not proportional
ANSWER:
they are not proportional
