SAVE IT, CHANGE IT, FLIP IT.

That is all you need to remember when dividing fractions. Easy as 1, 2, 3.  Seriously, it's almost as easy as multiplying; you just need to add one more step, multiply by the reciprocal of the 2nd fraction. Let's look at this example:


5/9 / 1/4 SAVE IT.
Keep the first fraction the same
5/9 x 4/1CHANGE IT and FLIP IT.
Change the division sign to a multiplication sign.
Take the reciprocal of the second fraction.
20/9 =Now, multiply and reduce as usual
2 2/9And here's our answer.

Look Out: always flip the second fraction, not the first!
