Dividing Fractions

To help us better understand what happens when we divide fractions, we like to imagine them as pizzas or legos.

INTRO
β€”
Any time we divide a number by a second number, we’re really just trying to answer the question: how many times does the second number go into the first number?
QuestionMeaningAnswer
How many 's are in ?
We can see that to divide, we actually just multiply the first number by the second number flipped.This works for all numbers, including fractions:

Step 1. Make sure both numbers are fractions.

Both of our numbers are already fractions, so we can skip to Step 2.

Step 2. Flip both the sign and the second fraction.

Step 3. Multiply across the top.

Step 4. Multiply across the bottom.

Step 5. Simplify (if needed).

How to Divide Fractions

Step 1. Make sure both numbers are fractions.

If multiplying a fraction by a whole number, convert the whole number to a fraction by placing it over . Otherwise, move onto Step 2.

Step 2. Flip both the sign and the second fraction.

Step 3. Multiply across the top.

Step 4. Multiply across the bottom.

Step 5. Simplify (if needed).

Dividing Fractions

Division is all about finding how many times a number goes into another number.

We can solve division problems that include fractions by remembering that a number divided by a second number is equal to the first number multiplied by the reciprocal of the second number.

Now that we know what to expect when we divide fractions, let’s check out some examples of how to divide fractions!

EXAMPLE 1

Let's start by finding the answer to:

Step 1. Make sure both numbers are fractions.

Both of our numbers are already fractions, so we can skip to Step 2.

Step 2. Flip both the sign and the second fraction.

Step 3. Multiply across the top.

Step 4. Multiply across the bottom.

Step 5. Simplify (if needed).

The final answer is .

EXAMPLE 2

Nice work! Now, let's find the answer to:

Step 1. Make sure both numbers are fractions.

Our second number is not a fraction, but we can make it one by putting it over .

Step 2. Flip both the sign and the second fraction.

Step 3. Multiply across the top.

Step 4. Multiply across the bottom.

Step 5. Simplify (if needed).

The final answer is .

EXAMPLE 3

Amazing job! Last one - let's find the answer to:

Step 1. Make sure both numbers are fractions.

Both of our numbers are already fractions, so we can skip to Step 2.

Step 2. Flip both the sign and the second fraction.

Step 3. Multiply across the top.

Step 4. Multiply across the bottom.

Step 5. Simplify (if needed).

The final answer is .

Question 1 of 10:

Step 1. Make sure both numbers are fractions.

Since both numbers are already fractions, we can just move on to Step 2.
Turn the whole number into a fraction:


Step 2. Flip both the sign and the second fraction.

The division () sign becomes a multiplication () sign, and the top and bottom numbers of the fraction swap positions.




Step 3. Multiply across the top.




Step 4. Multiply across the bottom.



Step 5. Simplify (if needed).



Great work! Our answer is .
