Answer 1

Hi friend!!!

Let x-4 be the numerator and x be the denominator of a fraction

→Given , If 1 is added to both its numerator and denominator, it become 1/2

→(x-4+1)/(x+1)=1/2

by cross multiplying, we get

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

2x-6=x+1

x=7

so, x-4 will be 7-4=3

so, the required fraction is 3/7

I hope this Will help u ;)

Happy learning

Answer 2

$Hi \:$

Let x-4 be the numerator and x be the denominator of a fraction.

⏩ Given, If 1 is added to both its numerator and denominator, it become 1/2

⏩ (x-4+1) / (x+1) = 1/2

By cross multiplying, we get

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

2x-6 = x-1

x=7

So, x-4 will be 7-4=3

⏩The required fraction 3/7
