If 1 is added to the denominator of a fraction the fraction becomes 1/2.if 1is added to the numerator of the fraction ,the fraction becomes 1. find the fraction

Let p/q be the original fraction. We know that:

We deduce that:

If we plug q=p+1 in the first equation, we have

and we deduce q=3.

In fact, if we start from 2/3, adding 1 to the denominator gives 2/4=1/2

Adding 1 to the numerator gives 3/3=1.

i think this could be a possible answer (1 / 84) -1

good luck! : d

the correct is answer is a 9-sided polygon!
