prove by mathematical induction that 7^n+4^n+1 is divisible by 6

Geometry
my geometry problem set says "find the ratio of CG : CB" CG=6.3 and CB=19 so to find the ratio i would divide the 19 by 6.3 (we have to round so it would be a 3:1 ratio) or would it be the other way around? i think it's the 19/6.3 but i'm not sure...
