    replace the variables with the numbers.

    48/(3/4)

    remember that 'division' is 'invert and multiply' equivalent.

    48 / (3/4)
    48 (4/3)
    48 (4) /(3)
    192/3
    64.

    Just put it one besides the other.



    Now, reverse:



    Then you multiply like you use to do with normal fractions. You should get 6.4.

    since they wrote the question with a 48 one time, and a 4.8 the other time, there is no way of know which one they are asking, but if they do the steps I recommended they can solve any problem of this type. The steps are to review, replace the variables with the numbers in the equation. Then solve.

    Yes, I just put it in a more visual way :)
