Question

Azure solved this proportion as shown: 12 30 = 5 x Step 1: 30x = (12)(5) Step 2: 30x = 60 Step 3: x = 2 What was Azure's error? In Step 2, she did not multiply 12 by 5 correctly. In Step 1, she multiplied the numerators together and the denominators together. In Step 1, she should have multiplied 5 by 12 instead of 12 by 5. In Step 3, she did not divide each side by the same number.
