The fraction is (6.75/7.25).

Step-by-step explanation:

We are given that the sum of the numerator and denominator of a fraction is 14. If 2 is added to numerator and 2 is subtracted from denominator it becomes 5/3.

Let the original fraction be \frac{x}{y}  where numerator = x and denominator = y .

We are given with the following conditions;

  • First condition states that the sum of the numerator and denominator of a fraction is 14, that means;

                                x+y=14

                                 x=14-y    ------------ [Equation 1]

  • Second condition states that if 2 is added to numerator and 2 is subtracted from denominator it becomes 5/3, that means;

                                 \frac{x+2}{y-2}=\frac{5}{3}

                          3(x+2) =5(y-2)

                             3x+6 =5y-10

                             3(14-y)+6 =5y-10         {using equation 1}

                             42-3y+6 =5y-10

                              48-3y =5y-10

                                 5y+3y =48+10

                                  8y=58

                                   y=\frac{58}{8}=7.25

Now, putting value of y in equation 1, we get;

                         x=14-7.25

                            = 6.75

Therefore, the original fraction is \frac{x}{y} =\frac{6.75}{7.25} .
