# The denominator of a rational number is greater than its numerator by 8. If the numerator is increased by 17 and denominator is decreased by 1, the number obtained is 3/2. Find the rational number.

Let the numerator of the rational number be x.Hence,the denominator=x+8.

According to the question,

(x+17)/(x+8-1)=3/2

x+17/x+7=3/2 =>2x+34=3x+21=>x=13.

Thus,the numerator is 13 and the denominator is 13+8=21.

let numerator be x                                                                                                                                                  then denominator will be x+8

x+17/x+8-1=3/2

x+17/x+7=3/2

2{x+17}=3{x+7}

2x+34=3x+21

34-21=3x-2x

13=x

x/x+8=13/21

if the numerator=x

then the denominator=x+8

the fraction=x/x+8

if numerator is increased by 17&denominator is decreased by 1then the fraction is

x+17/ x+8-1=x+17/ x+7

x+17/ x+8=3/2

cross multiplication

=2(x+17)=3(x+8)

=2x+34=3x+24

3x-2x=34-24

x=10

numerator=x=10

denominator=x+8=18

sorry x+17/x+7=3/2

2(x+17)=3(x+7)

2x+34=3x+21

x=34-21

x=13

numerator=x=13

denominator=x+7=21

Let the numerator be x so the denominator is x +8
Now according to the question (x+17 )/(x + 8 -1) =3/2
=>     (x+17)/(x+7) = 3/2
=>    2(x+17)=3(x+7)
=>    3x -2x = 34 -21
=>    x = 13
So the rational number is 13/21

let the numerator be x
a/q
x+17/x+8-1=3/2
now cross multiply x+17/x+8-1 with 3/2

=>2(x+17)=3(x+8-1)

=>2x+34=3x+24-3

=>34-24+3=3x-2x

=>13=x

hence the rational number is 13 is

Let the numerator be x
denominator= x+8
Acc. to question
Numerator is increased by 17= numerator= x+17
Denominator is decreased by 1= denominator = x+8-1=x+7
x+17/x+7=3/2
by cross multiplication : 2(x+17)= 3(x+7)
= 2x+34=3x+21
= 3x-2x=34-21
= x=13
numerator = x=13
denominator = x+8= 13+8=21
hence ,the rational number is 13/21

Let the numerator of the fraction on be x.
Therefore,denominator of fraction=x + 8.
Again,orginal fraction= x / x + 8
According to the given condition,
X + 17 / (x + 8) -1= 3/2
X + 17 / x + 7= 3/2
2 ( x + 17 ) = 3 ( x + 1)
2x + 34 = 3x + 21
2x - 3x = 21 - 34
-x = -13
x =13
Fraction = 13 / 13 + 8 = 13/21

Let numerator=x Then denominator= x+8 If denominator is decreased by 1and numerator is incresed by 17 Then, numerator=x+17 denominator=x+8-1=x+7 So, According to the question, (x+17)/(x+7)=3/2 =2(x+17)=3(x+7) =2x+34=3x+21 =2x-3x=21-34 =-x=-13 =x=13 Therefore, Numerator=x=13 Denominator=x+8=13+8=21 So, The rational number=Numerator/Denominator The rational number=13/21 (Ans.) I HOPE THAT MY ANSWER WILL HELP YOU...

Let the numerator be x and the denominator be x+8.
Given that:
x+17/ x+8-1 = 3/2
x+17/ x+7 = 3/2
3(x+7) = 2(x+17) ( by cross multiplication)
3x+21 = 2x+34
3x-2x = 34-21
x = 13
Then, the rational no.= x/ x+8
= 13/21

Hope this helped:)

Let numerator be x+17
Let denominator be x+8-1
x+17/x+7=3/2
By cross multiplication,
3(x+17)=2(x+7)
3x+51=2x+14
3x-2x = 14-51
x=-37
Numerator = x+17=-37+17=-20
Denominator= x+7=-37+7= -30

Let the numerator of the fraction on be x.?
Therefore,denominator of fraction=x + 8.?
Again,orginal fraction= x / x + 8?
According to the given condition,?
X + 17 / (x + 8) -1= 3/2?
X + 17 / x + 7= 3/2?
2 ( x + 17 ) = 3 ( x + 1)?
2x + 34 = 3x + 21?
2x - 3x = 21 - 34?
-x = -13?
x =13?
Fraction = 13 / 13 + 8 =
