May I please get help with this. I have tried multiple times but still could not get the right answer

Answer:
4/1
Explanation:
To calculate the scale factor of the model to the bridge, we need to divide the dimensions of the bridge by the dimensions of the model, so
24 / 6 = 4
32 / 8 = 4
36 / 9 = 4
Therefore, the scale factor is 4. Written as a fraction is 4/1.
So, the answer is 4/1
