At an ice skating rink, there are 22 people who know how to ice skate and 18 people who do not know how to ice skate. what is the ratio of people who know how to ice skate to people who do not know how to ice skate?

The ratio is 22:18 like duhhh lol

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
