    well AC is the same as FD and since AC = 8 and FD = 4, 8 is double 4 so all measurements in ABC are double DEF

    also since BC = 12 and EF is half of that EF has to be 6

    These are the choices 3:1 1:3 2:1 1:2

    oh they're trying to be tricky by mixing up the order of the triangles. its D 1:2

    2:1 would be correct if they asked whats the ratio between ABC and DEF

    but they asked the other way around DEF to ABC, therefore its 1:2
