The denominator of a rational no. is greater than its numerator by 8. If the numerator is increased by 17and the denominator is decreased by 1 ,the no. obtained is 3/5.Find the rational no.

Given,
x/(x+8) = Rational no.
Also,
(x + 17)/ ( x + 8 - 1) = 3/5
so,
5(x + 17) = 3(x + 7)
Solving,
2x = -64
so, x is -32....
Hence, the rational number is
-32/{8 + (-32)}
= -32/-24
= 4/3
Hope this helps....

No probs....
not hungry for points
thank u i thought that u were hurted
not at all.... who cares. I'm here just to help and gain some knowledge.... : )

let the numerator be x then denominator will be x+8 and the fraction obtained will be x/x+8 now increase the numerator and denominator by 17 so, x+17/x+8+17=x+17/x+25
X+17/x+25=3/5
then,5x+85=3x+75
5x-3x=-10
x=-5
the rational no. is
x/x+8=-5/3
X+17/x+25=3/5
then,5x+85=3x+75
5x-3x=-10
x=-5
the rational no. is
x/x+8=-5/3
mark it as brainliest please
his answer is wrong
Sir your answer is wrong u haven't decreased 1 from the denominator instead of doing that u have added 17 with both the numerator and denominator
sorry but idid hard work please mark my answer brainliest
i have never got my answer brainliest from three years
i follow ypu
there is no need to do that
o you are so kind hearted
