Answer:

B & C

Step-by-step explanation:

2:9 can also be written as 2/9

A. 9:2 is just the reciprocal of 2:9 so it is not equivalent to it

B. 18:81 is 2×9:9×9 meaning that is equivalent to 2:9

C: 12:54 is 2×6: 9×6 so it is equivalent to 2:9

Since the two correct answers have already been found, I don't need to explain more.

Hope this helped!!!
