Hi, can you help me with a math problem kbin? It's algebra, and it's been a long time since I've had to do it. Can you explain to me how simplifying the terms comes out to 9/2 in the pictured equation (media.kbin.social)

Reciprocal is the fraction that, multiplied by the original, would give you 1. For example, the reciprocal of 2/3 is 3/2. If you multiply them you get 6/6, which is 1. It's the same for 9/2 and 2/9. I always think of it is the "opposite fraction", where you just flip the top and bottom numbers around.
