Answer:
The fraction is
Step-by-step explanation:
Let the numerator be x and denominator be y
So, Fraction = 
Now we are given that numerator and denominator of the fraction is increased by 2 and 1 respectively. it becomes 3/4
So, Fraction becomes :


----1
We are also given that the numerator and the denominator are decreased by 2 and 1 respectively , it becomes 1/2
So, Fraction becomes :


---- 2
Substitute the value of y from 2 in 1




Substitute the value of x in 2



So, Fraction = 
Hence The fraction is
NO is 2 times LM
2(x+1) = 4x
2x + 2 = 4x
2 = 2x
1 = x
Plug that in for 4x
4(1)
