Answer:
I would honestly choose 9
Step-by-step explanation:
Because it is using cross products and you want them to equal the same, so you take 6 x 12= 72 so you take 8 and multiply by each number Each time you know 72 x 8 wont work and the 576 wont work and that .75 is going to be way too little therefore its 9 and you can check by multiplying 8 x 9= 72
