 Oct 09, 2010 Dividing Fractions by: Staff The question: a/b divided by c/d The answer: a/b divided by c/d = (a/b)/(c/d) = (a/b) * (d/c) = (a*d)/(b*c) = ad/bc If you would like an explanation, it is this: Any number multiplied by 1 is still the original number. Multiplying by 1 does not change its value. A number divided by itself is = 1 1 = the fraction (d/c)/(d/c) Your original question is: (a/b)/(c/d) Multiply your original fraction by the fraction (d/c)/(d/c). Note that (d/c)/(d/c) = 1. [(a/b)/(c/d)] * [(d/c)/(d/c)] = [(a/b)*(d/c)] / [(c/d)*(d/c)] The fractions in the denominator cancel one another [(c/d)*(d/c) = 1] = [(a/b)*(d/c)] / 1 = (a/b)*(d/c) = (a*d)/(b*c) = ad/bc Thanks for writing.
