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

**Ms. Sue**, Tuesday, April 15, 2008 at 9:17pmRenaming fractions:

1/2 / 1/4 = 2/4 / 1/4

Divide numerators:

2 / 1 = 2

That seems to be what your question is asking.
