Question

numerator of a friction is 4 less than the denominator .If 1is added to both numerator and denominator the friction becomes 3/4 .Find it​

Answer 1

Answer:

let De of fraction = x

Nu. =x-4

A.T.Q

x-4+1/x+1=3/4

x-3/x+1 =3/4

4(x-3)=3(x+1)

4x-12 =3x+3

4x-3x =3+12

x. = 15

so Nu = 15-4 =11

De. = 15

and Fraction = 11/15
