The original fractionis
Explanation of Solution
Given information:
The numerator of a fraction is
And numerator and denominator is both increased by
Formula used:
Wewill use
We will us L.C.M of the denominator.
We will use cross multiplication method.
Calculation:
Consider that the denominator is
Then the original fraction is
Now the numerator and denominator is increased by
Then the fraction is
Recall that we will take the L.C.M of the denominator
Therefore
Therefore on further solving we have
Recall that we will use cross multiplication method.
Recall that we will use quadratic equation
Where
Therefore
Therefore the original fraction is
