the denominator of a fraction is greater than numerator by 8. if the numerator is increased by 17 and denominator is decreased by 1. the number obtained is 3/2. find the fraction.



Sagot :

let 'x' be the numerator
     'x+8' be the denominator
[tex] \frac{x+17}{x+8-1} = \frac{3}{2} [/tex]
[tex] \frac{x+17}{x+7} = \frac{3}{2} [/tex]
2(x+17) = 3(x+7)
2x + 34 = 3x + 21
3x- 2x = 34 - 21
x = 13
for the denominator
x + 8 = 13 + 8
         = 21
the fraction therefore is:
[tex] \frac{13}{21} [/tex]
