The answer is 110. (Brainly isn't letting me use 'enter', I don't know why) Basically you can cross multiply to get 990 = 9x. Divide both sides by 9 to get 110. Or you can just scale up by multiplying the fraction on the left side by 10/10 to get 90/110. I hope I helped! If it did, feel free to give me a 'brainliest answer'.
