    divie \(6\) by \(\frac{2}{4}\) which is the same as multiplying \(6\) times \(\frac{4}{3}\)

    tell your teacher satellite73 said there is no such mathematical operation as "cross multiply" and to remove that from his or her vocabulary

    in any case your job is to compute \[\large 6\div \frac{3}{4}=6\times \frac{4}{3}\]

    Honestly rounding that was mental math and it is close to the answer and it is cross products

    Sorry for the weird scribbles. Although you wouldn't really use cross multplication here because there are no variables in the fractions.
