The Singing Hedgehog Guide to:
Dividing Fractions 2

As with multiplying with mixed numbers, here too we need fractions first.

Once we just have two fractions we can:

LEAVE IT, CHANGE IT, FLIP IT!

A final example:

 
 
Write out the question

 Turn mixed into top-heavy
     1 times 5 is 5 add 1 gives 6
     2 times 7 is 14 add 4 gives 18


 Do the magic phrase:
     leave the first fraction
     change the sign to times
     
flip the second fraction
 
 Now we just have a times question to do
 Find common factors (numbers to divide by)
 
 5 and 7 can't simplify further so we leave them
 
6 and 18 are both divisible by 6 to leave 1 and 3

 Multiply across
 
Job done!
