Step-by-step explanation:
Answer:
Original fraction = 6/14 .
Step-by-step explanation:
Let numerator be x and denominator be y.
First condition says that If numerator is multiplied by 3 and 3 is subtracted from the denominator then the fraction obtained is 18/11 i.e.;
\frac{x*3}{y-3}= \frac{18}{11}
y−3
x∗3
=
11
18
33 * x = 18(y - 3)
33*x = 18*y - 54
11*x = 6*y - 18 ---------- [Equation 1]
Second condition says that If numerator is increased by 8 and denominator is doubled then the resulting fraction is 1/2, i.e.;
\frac{x+8}{2y} = \frac{1}{2}
2y
x+8
=
2
1
2(x + 8) = 2*y
x + 8 = y
x = y - 8 ----------- [Equation 2]
Now, putting value of x from equation 2 into equation 1, we get;
11(y - 8) = 6*y - 18
11*y - 88 = 6*y - 18
11*y - 6*y = 88 - 18
5*y = 70
y = 14 and so x = 14 - 8 = 6
Therefore, numerator, x = 6 and denominator, y = 14 .
