Question

if we add 1 to the numerator and substract 1 from the denominator,a fraction reduces to 1.It becomes 1 by 2 if we only add 1 to the denominator.what is the fraction

Answer 1

Answer:

3/5

Step-by-step explanation:

Let the numerator be x and denominator be y ∴ fraction = x/y

According to question

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

x + 1 = y - 1

x = y - 2 ---- ( i )

Also

x/ ( y + 1) = 1/2

2x = y + 1

Putting value of x from ( i )

2 ( y - 2) = y + 1

2y - 4 = y + 1

y = 5

Putting value of y in ( i )

x = 5 - 2

x = 3

∴ Desired fraction is 3/5
