Answer 1

Let the fraction be X/Y

Original fraction = X/Y

Given,

X+8/2Y = 1/2

2(X+8) = 2Y

X+8 = Y

Y - X = 8

Answer 2

Let numerator be x

and, denominator be y

then, fraction will be x/y

Now, numerator is increased by 8.

so, new numerator is x+8.

and, denominator is doubled

so, new denominator is 2y

it is also given that th fraction becomes 1/2

therefore, x+8/2y = 1/2

2x+16 = 2y

2x-2y+16=0

x-y+8=0..............On dividing both sides by 2.

x-y = -8

y-x = 8.




Hence the linear equation in two variable to find the fraction of given data is:-
y-x = 8.
