Question

if the numerator of a fraction is multiplied by 3 and 3 is substrated from the denominator we get 18/11 .if 8 is added to the numerator and the denominator is doubled we get 2/5. find the fraction ( its urgent)​

Answer 1

Answer:

let numerator is x and denominator is y

Step-by-step explanation:

3x/(y-3)=18/11

x+8/2y=2/5

4y =5x+40

y=(5x+40)/4

3x/(y-3)=18/11

33x=18y-54

33x-18y= -54

33x-18.(5x+40)/4= -54

132x-90x-720= --216

42x= -216+720

42x=504

x=504/42=12

y=(5x+40)/4=(5.12+40)/4

=100/4=25

so the fraction. is 12/25
