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!
