Geometric sequences use either division or multiplication as the common ratio. The third choice down has a common ratio of 3. 1*3=3, 3*3=9, 3*9=27, etc.
Answer:
By multiplying each ratio by the second number of the other ratio, you can determine if they are equivalent. Multiply both numbers in the first ratio by the second number of the second ratio. For example, if the ratios are 3:5 and 9:15, multiply 3 by 15 and 5 by 15 to get 45:75.
