Explanation:
A ratio is a comparison between two or more numbers.
When two ratios are equivalent, they describe the same relationship between numbers.
An equivalent ratio is to a number is usually the same ratio in which the numerator and denominator (first and second number) have been multiplied by a common multiple.
To find if two ratios are equivalent, we have to put them in their simplest forms and compare.
The ratio we are comparing other ratios with is 2:9
So, we will put all other ratios in their simplest form and see if it gives us 2:9
