    Hint: add the two fractions you have in the numerator (and then in the denominator) and then use the reciprocal rule to divide the results

    You can always doublecheck your answers at wolframalpha.com, but that sounds right... multiplying both numerator and denominator by 3*4=12 would also have worked

    since simplifying top then bottom will result in fraction you mulitply by reciprocal
