Question 700161: I am working on mixed numbers and variables in fractions. The problem is Solve for x: (2 1/2)/24)=x/30
I'm not quite sure how to start. Do I multiply both sides by 24 to leave the mixed number by its self which would give me 2 1/2 = 3x/5 then multiply the both sides by 5 to get 25/2 = 3x then divide by 3 to get 25/6. Or do I change the mixed number to a decimal so it is 2.5/24 = x/30. I'm just really confused...
