Question

The denominator of a fraction is greater than its numerator by 7 if 4 is added to both it's numerator and denominator then it becomes 1\2. find the fraction​

Answer 1

Answer:

3/10

Step-by-step explanation:

Let the fraction be x / y

And y = 7 + x

Now new fraction be (x + 4 )/ (y + 4)

X + 4 / y + 4 =1/2

2 X + 8 =y + 4

2 X + 8 = 7 + X + 4

X is equal to 3 and y equal to 10

So the fraction is 3/10
