Yes because 7 to 9 is proportional for 70 to 90
Your question is incomplete... proportional to WHAT?
No, 8/17 and 7/10 are not proportional.
Yes. It is inversely proportional. An increase in x results in a proportional decrease in y and vice versa.
x*y = k where k is a constant.When x = 9, y = 7 so k = 9*7 = 63 When x = 21, 21*y = 63 so y = 3.

Your question is incomplete... proportional to WHAT?
No, 8/17 and 7/10 are not proportional.
No. 8 to 9 is proportional to 16 to 18, not 18 to 16.

To determine if two ratios are proportional, we cross multiply and check if the products are equal. In this case, 8 * 4 = 32 and 9 * 3 = 27. Since 32 is not equal to 27, the ratios 8 to 9 and 3 to 4 are not proportional.

No.
Yes. It is inversely proportional. An increase in x results in a proportional decrease in y and vice versa.
No.
The gravitational force between two objects decreases by a factor of 9 if the distance between the objects is tripled. This is because the gravitational force is inversely proportional to the square of the distance between the objects.
