Step-by-step explanation:

let the denominator be X

numerator will be x-2

x-2/x

x-2+1/x+1=3/4

x-1/x+1=3/4

4x-4=3x+3

x=7

x-2=7-2=5. x=7

Step-by-step explanation:

let the no be x .

so according to given condition,

x-2/x

if we increased 1 in numerator and denominator the fraction is 3:4,so according to given condition it becomes.

x-2+1/x+1=3:4

x-1/x+1=3:4

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

4x-4=3x+3

4x-3x=3+4

x=7
