@The_Beast_Eli: I've asked you before NOT to provide direct answers to the question of others. If you know how to solve a problem, guide the other person towards finding his or her own answers. Thank you.

@Electronia : Look at the original proportion: 18/30. Reduce this by dividing numerator and deonominator by the greatest common factor. Please show your work.

Then, do the same with the answer choices 20/35,50/90,36/48 and 60/100 Does the reduced original ratio match any of the reduced ratios from which you are asked to choose?

Hint: 60/100 reduces to 3/5 if you divide both 60 and 100 by the GCF, 20.

My suggested method is just one of several available to you. You could take the given ratio, 18/30, and cross-multiply it by any of the possible answers. Are the 2 products equal? If yes, you've found a pair with the same ratio. If not, you haven't.

Please explain what you do and what you do not understand. We'll go from there.

60/100 = 60% = 0.6

While technically correct, your decimal ratio ().6) is not in the same form as is the given 18/30. Either convert 0.6 to a proper fraction for comparison purposes, or convert 18/30 to a decimal fraction (for the same purpose).
