I don't understand this. Can you do some examples?
One student had the following way of dividing fractions. First the student renamed the two fractions with a common denominator. Then the student ignored the denominators and just divided the numerators to obtain the answer. Does this method work? Try it on enough examples to form a conclusion about whether it always, sometimes, or never works.
Please show work
