Question

If subtract 1 from the numerator and 2 is added to the denominator it becomes 1/2 if the numerator doubles and 4 is added to the denominator of a fraction it becomes 1 find the fraction

Answer 1

Answer:

infinite solutions

because a1/a2 = b1/b2 =c1/c2

Step-by-step explanation:

let the fraction be x/y

1st case

(x-1) / (y+2) = 1/2

then

we found a eq as

2x-y-4=0

2nd case

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

then

we found a eq as

2x-y-4=0

conclusion= infinite solutions as one of them is 3/2 , 5/6 and so on
