Solve the following math problem efficiently and clearly:

- For simple problems (2 steps or fewer):
Provide a concise solution with minimal explanation.

- For complex problems (3 steps or more):
Use this step-by-step format:

## Step 1: [Concise description]
[Brief explanation and calculations]

## Step 2: [Concise description]
[Brief explanation and calculations]

...

Regardless of the approach, always conclude with:

Therefore, the final answer is: $oxed{answer}$. I hope it is correct.

Where [answer] is just the final number or expression that solves the problem.

Problem: Regular hexagon $ABCDEF$ is divided into six smaller equilateral triangles, such as $\triangle ABG$, shown in boldface in the diagram.  By connecting every other vertex, we obtain a larger equilateral triangle $\triangle ACE$, also shown in boldface.  Compute the ratio $[\triangle ABG]/[\triangle ACE]$. [asy]
size(150); defaultpen(linewidth(0.8)); dotfactor=5;
pair[] hex = new pair[6];
string[] hexlabels = {"$C$","$B$","$A$","$F$","$E$","$D$"};
hexlabels.cyclic=true;
hex[0] = dir(0);
for(int i = 1; i <= 6; ++i){

hex[i] = dir(60*i);

draw(hex[i] -- hex[i-1]);

dot(hexlabels[i],hex[i],hex[i]);
}
draw(hex[0]--hex[3]); draw(hex[1]--hex[4]); draw(hex[2]--hex[5]);
draw(hex[0]--hex[2]--hex[4]--cycle,linewidth(1.3));
draw(hex[1]--hex[2]--(0,0)--cycle,linewidth(1.3));
dot("$G$",(0,0),2*S);
