Let the numerator be A and the denominator be B. So, the required fraction is $A/B$. ATQ, The sum of the numerator and denominator of the fraction is $12$. $A+B=12$ ⇒ $A+B–12=0$ ATQ, If $3$ is added...

If denominator is decreased by $1$ and numerator is increased by $1$, a fraction becomes $1$. It also becomes $\frac{1}{2}$ if we only increase the denominator by $1$. So now find the fraction?

Let the numerator of the fraction to be A and the denominator of the fraction to be B. So, the required fraction is $A/B$. ATQ, Thus, the equation so formed is, $(A–1)/(B−1)=1/3$ ⇒ $3(A–1)=(B–1)$ ⇒...

The denominator of a fraction is $4$ more than the numerator. If the denominator is eight times the numerator then the numerator is lessen by $2$ and denominator is increased by $1$. Find the original fraction calculated.
