In a fraction, if numerator is added by 2 and denominator by 1 it results 1, and if numerator added again by 4 and denominator by 2 it results 1/2. Find the fraction?

• solution:
  x+2/y+1 =1 i.e, x-y+1=0;--------(1)
  x+4/y+2 =1/2 i.e., 2x-y+6=0;---------(2)
  solving 1 and 2...we get x= -5 and y= -4
  answer is 5/4...

• let numerator=x and denominator=y
  according to question,
  (x+2)/(y+1)=1
  =>x+2=y+1
  =>x-y= -1....................................(eq 1)
  and
  
  (x+2+4)/(y+1+2)=1/2
  =>(x+6)/(y+3)=1/2
  =>2x+12=y+3
  =>2x-y= -9..................................(eq2)
  
  solving equation 1&2,we get
  x= -8 & y= -7
  
  so fraction is
  -8/-7 =8/7.............answer..:)

• x+2/y+1=1
  x+2=y+1
  x-y=-1
  
  so, the ans is -8/-7
  
  x-y=-1
  -8+7=-1
  thats y ans is -8/-7...

• let numerator=x and denominator=y
  so (x+2/y+1)=1 ie
  x-y+1=0 ------(1)
  and again add 4 and 2 in numerator and denominator
  2x-y+9=0 ------(2)
  and by solving 1 and 2 eqation we get ,
  x/y=8/7

• X+2/y+1=1,x+2+4/y+1+2=1/2,,,,
  By solving x=-8,y=-7,
  So fraction =8/7

• x+2/y+1 = 1;
  x+2=y+1
  x-y=-1;
  
  x+4/y+2=1/2;
  2x+8=y+2;
  2x-y= -6;
  
  solve it
  x=5, y= 6

• n+2/d+1=1 =>n+1=d
  n+1/d+2=1/2 =>d=2n+6
  so n+1=2n+6 =>n=-5
  and substituting the values of n d=-4
  so n/d=5/4

• eq formed will be,x-y=-1
  2x-y=-6
  solving we get,x/y=5/4

• -8/-7
  Let numerator be x and denominator be y
  2x+12=y+3
  x+2=y+1
  Solving this we get x=-8 and y=-7

• answer is -8/-7
  ((-8+2)/(-7+1))=1
  ((-8+6)/(-7+3))=1/2
