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