Let AD be 10 i.e AB = 5 and BD = 5 (AD = AB + BD as B is mid point)

Now C is midpoint for BD, BD = BC + CD.

As per our values BD = 5 then BC = 2.5 and CD = 2.5

$$\frac{AB}{AC}$$
=> $$\frac{5}{5 + 2.5}$$ ( Note : AC = AB + BC )
=> $$\frac{5}{7.5}$$
=> $$\frac{1}{1.5}$$
=> $$\frac{1}{(3/2)}$$

=> 2/3.
