The numerator of a fraction is 4 less than the denominator. If I is added to both its
numerator and denominator, it become 1/2find the fraction​

Answer 1

Answer:

Step-by-step explanation:

Let denominator be x

numerator becomes x-4

According to the condition

1+numerator/1+denominator = 1/2

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

x+1-4/x+1 = 1/2

x-3/x+1 = 1/2

2(x-3) = 1(x+1)

2x-6 = x+1

2x-x = 1+6

x = 7

denominator = 7

numerator = x-4 = 7-4 = 3

Fraction is 3/7
