The correct answer is 54 rails.

Step-by-step explanation:

Max builds rail fences. For one style of fence, each section uses 3 vertical fence posts and 6 horizontal rails.

For every style of fence Max uses 3 vertical fence posts and 6 horizontal rails.

For every style of fence Max uses vertical fence posts and horizontal rails in the ratio of 1 : 2.

Max uses 27 posts. Therefore he needs to use 27 * 2 = 54 rails.

Therefore Max needs 54 rails for a fence that has 27 posts.
