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!
