Answer:

Below

Explanation:

Original fraction (x-1) / x <====given (use in final step below)

Altered fraction (x-1 +1) / (x+5) = 1/2 <====solve this for 'x'

x / (x+5) = 1/2 cross multiply

2x = x+5

x = 5

So original fraction was 4/5

Answer:

original fraction =
(4)/(5)

Explanation:

let the denominator of the fraction be x then the numerator is x - 1 , so

original fraction is


(x-1)/(x)

if 1 is added to the numerator and 5 to the denominator , then fraction is


(-1+1)/(x+5) =
(x)/(x+5)

equate this to
(1)/(2)


(x)/(x+5) =
(1)/(2) ( cross- multiply )

2x = x + 5 ( subtract x from both sides )

x = 5

then original fraction is


(x-1)/(x) =
(5-1)/(5) =
(4)/(5)
