The denominator of a fraction is 3 more than its numerator.

When  12   is added to this fraction, the resulting fraction's denominator is twice the denominator of the original fraction and its numerator is 1 more than its denominator.

What is the numerator of the original fraction?

What is the numerator of the original fraction?

 

Let the fraction be    \(\frac{a}{a+3}\)

 

\(\frac{a}{a+3}+12 =\frac{a+12(a+3)}{a+3}=\frac{13a+36}{a+3}=\frac{2(13a+36)}{2(a+3)}\)

 

 

The meaning of the question is very unclear.

I've tried a couple of different versions an none make sense.

 

This question,as far as I can tell, is a garbage question.

I think I posted an answer to this question yesterday....and it is   1/2   NOT 12 that is added to the fraction:
