Question

The sum of the numerator and
denominator of a fraction is 8.if 3
is added both of the a nomerator
and the denominator, the fraction
become 3/4 find the fraction​

Answer 1

Answer:

let numerator be x

and denominator be y

x+y..=8...............eqn1

3+x+3+y=3/4

6+x+y=3/4

x+y=3/4-6

x+y=-21/4

Answer 2

Answer:

Step-by-step explanation:

let, numerator be x

     denominator be y

           A.T.Q

x + y = 8                           .....(1)

 x +3 /y +3 = 3/4             ......(2)

 from eq. (1)

  x=8-y                             .......(3)

putting value of x in eq. (2)

 8 - y +3/ y+3 = 3/4

 11-y/y+3=3/4

cross multiplication

11-y*4=y+3*3

44-4y=3y+9

44-9=3y+4y

35=7y

35/7=y

y=5

          putting value of y in eq.(3)

x=8-5

x=3

Hence, fraction is 3/5
