    Answer:

    numerator be x

    so denominator is 12-x

    then,add 1 in both

    the numerator is x+1

    and denominator is 12-x+1

    and given new fraction is 3/4

    By question,

    or, x+1/12-x+1=3/4

    4 (x+1)=3 (12-x+1)

    4x+4=36-3x+3

    4x+3x=36+3-4

    7x=35

    x=35/7

    x=5

    so, numerator is 5

    and denominator is 12-5=7

    the fraction is 5/7
