You require at least two ratios for them to be equivalent (or not).
To find a ratio equivalent to 8 to 9, we need to find a common multiplier to scale both numbers. In this case, we can multiply both 8 and 9 by 2 to get 16 to 18, which is equivalent to 8 to 9. Therefore, the ratio equivalent to 8 to 9 is 16 to 18.
