Thank you for spending your time to help me. Answer by Theo(13342) (Show Source):
You can put this solution on YOUR website! see the attached worksheet and the words underneath.
first you change this into a multiplication problem because:
(a/b) / (c/d) = (a/b) * (d/c)
then you multiply the first fraction by a/a and you multiply the second fraction by b/b.
this removes the fraction parts of the numerators and denominators or each.
you then remove the parts of the numerator that cancel out with equal parts in the denominator.
the result is your answer.
you are using the associative law of multiplication when you multiply the first fraction by a/a and the second fraction b/b.
the associative law of multiplication says you can do the following:
a * b * c = (a * b) * c = a * (b * c)
a * b * c * d = (a * b) * (c * d)
