Solution:

Try taking the base of the triangle as 1 inch. Both of the sides are 3 inches.
And the portion required is

1.5 {/} 1=1.5

.
Try taking different numbers, take 10 inches as the length of the base.
The length of both sides is

(10+2=12

inches

)

.
The portion required is

6 {/} 10

.
We can see that a randomly pick of two numbers will give two different answers and therefore there is no distinct answer.
