  2. Let the numerator be x and denominator be y

    According to question,

    x-2/y=1/3

    3x-6=y…(1)

    x/y-1=1/2

    2
    x=y-1…..(2)

    Substitute eq.(1) in eq.(2)

    2x=3x-6-1

    2x-3x=-7

    -x=-7

    x=7

    Substitute this value in eq.(2)

    2x=y-1

    2(7)=y-1

    14+1=y

    y=15

    So fraction become 7/15
