In order to determine if two sets of numbers are proportional, you need to compare their ratios. For 7 and 9, the ratio is 7/9, which simplifies to 0.777. For 70 and 90, the ratio is 70/90, which simplifies to 0.778. Since these two ratios are not equal, 7 and 9 are not proportional to 70 and 90.
Yes. It is inversely proportional. An increase in x results in a proportional decrease in y and vice versa.
You CAN'T determine whether two numbers are proportional, just by looking at one number from each set.
9 over 16 is the same as 9 divided by 16: 9 ÷ 16 = 0.5625
Expressed as a decimal, 16/9 = 1.7 recurring (that is, 1.7777...)
Oh, dude, let me break it down for you. To check if two ratios are proportional, you just cross multiply and see if the results are equal. So, for 8 to 9 and 18 to 16, it's 8 x 16 = 9 x 18. And guess what? They're not equal, so nope, these ratios are not proportional. Like, it's simple math, man.

Yes, and they are the same fraction when reduced 24/27 = 8/9 ( divide numerator and denominator by 3) 16/18 = 8/9 ( divide numerator and denominator by 2)
9
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.
9
yes, they are.
Yes. It is inversely proportional. An increase in x results in a proportional decrease in y and vice versa.
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.
