Step-by-step explanation:
let the fraction is xy\dfrac{x}{y}
y
x
.
According to the given condition,
A fraction becomes 1/3 when 1 is subtracted from its numerator. So,
x−1y=133x−3=y3x−y=3 .....(1)\begin{lgathered}\dfrac{x-1}{y}=\dfrac{1}{3}\\\\3x-3=y\\\\3x-y=3\ .....(1)\end{lgathered}
y
x−1
=
3
1
3x−3=y
3x−y=3 .....(1)
The fraction becomes 1/4 when 8 is added to its denominator. So,
xy+8=144x=y+84x−y=8 .....(2)\begin{lgathered}\dfrac{x}{y+8}=\dfrac{1}{4}\\\\4x=y+8\\\\4x-y=8\ .....(2)\end{lgathered}
y+8
x
=
4
1
4x=y+8
4x−y=8 .....(2)
Solving equation (1) and (2) we get :
x=5x=5x=5
Put x = 5 in equation (1) :
3(5)−y=3y=12\begin{lgathered}3(5)-y=3\\\\y=12\end{lgathered}
3(5)−y=3
y=12
So, the fraction is 512\dfrac{5}{12}
12
