16) The ratios are proportional.

17) The ratios are not proportional.

Step-by-step explanation:

we need to determine if the ratios form the proportions.

16)

If the ratios are proportional, their cross product will be equal. i.e.

So, finding cross product and checking:

Since the cross product is equal i.e. 81=81 so, the ratios are proportional.

The ratios are proportional.

17)

If the ratios are proportional, their cross product will be equal. i.e.

So, finding cross product and checking:

Since the cross product is not equal i.e. 238≠225 so, the ratios are not proportional.

The ratios are not proportional.
