Oh, what a lovely question! To find out if two ratios are proportional, we can cross multiply and see if the results are equal. So, for 8 to 9 and 18 to 16, when we cross multiply (8 x 16 and 9 x 18), we see that they are not equal. That means these ratios are not proportional, but it's all part of the happy little journey of learning!

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.

No.

8 to 9 is proportional to 16 to 18, not 18 to 16.
