Hello there, and thank you for posting your question here on brainly.

Short answer: 1:3

Why?

A fraction is at it's largest when it's closest to zero. The option 1:3 is the closest to zero, all the others are equal to 2:9

Hope this helped you! ♥

1:3 because it's a third, I think cause it's kinda like fractions well named
