Let numerator be x,
Denominator be (x + 3)

fraction =  \frac{x}{x + 3}


×××××××××××××


When 5 is added to both, fraction becomes 4/5


 \frac{x + 5}{ x + 3 + 5}  =  \frac{4}{5}  \\  \\ 5(x + 5) = 4(x + 8) \\  \\ 5x  + 25 = 4x + 32 \\  \\ 5x - 4x = 32 - 25 \\  \\ x = 7 \\  \\  \\  \\  \\ original \: fraction \:  =  \frac{x}{x + 3}  =  \frac{7}{7 + 3} =   \frac{ 7}{10}





I hope this will help you

Heya ✋

Let see your answer !!!!!

Let the numerator be x. Then,

denominator = x + 3.

According to question ,

x + 5 / x + 3 + 5 = 4/5

=> x + 5 / x + 8 = 4/5

=> 5(x + 5) = 4(x + 8)

=> 5x + 25 = 4x + 32

=> 5x - 4x = 32 - 25

=> x = 7

Hence , numerator = 7 and

denominator = 7 + 3 = 10.

So , the original fraction = 7/10.
