If the numerator and denominator of the fraction is increased by 2an1 respectively; it becomes3/4 if the numerator and the denom
ipn [44]

Answer:

The fraction is\frac{7}{1}

Step-by-step explanation:

Let the numerator be x and denominator be y

So, Fraction = \frac{x}{y}

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 :\frac{x+2}{y+1}=\frac{3}{4}

4(x+2)=3(y+1)

4x+8=3y+3

4x-3y+5=0----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 :\frac{x-2}{y-1}=\frac{1}{2}

2(x-2)=y-1

2x-4=y-1

2x-y-3=0 ---- 2

Substitute the value of y from 2 in 1

4x-3(2x-3)+5=0

4x-6x+9+5=0

14=2x

7=x

Substitute the value of x in 2

2(2)-y-3=0

4-3=y

1=y

So, Fraction = \frac{x}{y}=\frac{7}{1}

Hence The fraction is\frac{7}{1}
