Answer 2

Answer:

Let the required integer be X

Given fraction =2/7

If X is added to the numerator then the fraction becomes (2+X)

If X is subtracted from the denominator then the fraction becomes (7-X)

Then the new fraction =(2+x)/(7-x )

According to the given problem

The new fraction =2

Right arrow(2^ . =>(2+X)/(7-X)=2

On applying cross multiplication then

=>2+X=2(7-X)

=>2+X=2*7-2* X

=>2+X=14-2X

=>X+2X=14-2

=>3X=12

=>X=12/3

=>X=4

Therefore X = 4

Answer:

The required integer for the given problem

is 4
