At a Glance - Dividing Fractions
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:
|SAVE IT. |
Keep the first fraction the same
|CHANGE IT and FLIP IT.|
Change the division sign to a multiplication sign.
Take the reciprocal of the second fraction.
|Now, multiply and reduce as usual|
|And here's our answer.|
Look Out: always flip the second fraction, not the first!
Division Example 1
Division Example 2
First, turn 10 into a fraction by placing over a denominator of 1.
Division Example 3
Change the mixed numbers into improper fractions.
A rule of thumb: if a problem initially presents a fraction as a mixed number, then the answer should be written as a mixed number, not an improper fraction.
