Question

Explain how to divide a over b divided by c over d

Answer 1

So a over b divided by c over d looks like the following

`(a)/(b)/(c)/(d)`

In order to divide two fractions, you multiply by the reciprocal (also known as the multiplicative inverse).

The reciprocal is the fraction "flipped"

`(a)/(b)/(c)/(d) = (a)/(b)*(d)/(c)\\(a)/(b)*(d)/(c) = (ad)/(bc)`

Answer 2

flip c over d to d over c and multiply it so:

`(a)/(b) * (d)/(c)`
