So that's an "o" not a "0"? Hmm, coulda fooled me. Anyways, start by dividing 9/10 from (9/10)x. Then, divide 9/10 from 6o. And you should remember that when dividing by a fraction you flip the top and bottom numbers and multiply that with (6o/1). Do the math and you get (60o/9). And depending on the teacher you can reduce that to 6 + (6o/9). PS I just put the () around stuff for clarification's sake, you dont really need to do that in the work. Have a nice day. :)
