How To Divide Fractions – The term “dividing fractions” can cause anxiety in almost anyone – you have to flip fractions and know the terms division, dividend, and reciprocal. Remembering the steps involved in dividing fractions may seem difficult, but with a little practice they become easy. Because math is all about remembering rules and conditions, and if you can do that, dividing fractions is much easier.
Division is the inverse of multiplication, so one thing you need to remember when dividing fractions is that the answer will always be larger than either part of the problem. You’re basically trying to figure out how much of the divisor (the second number in the problem) can be found in the dividend (the first number). If you know how to multiply fractions, you will have no problem learning how to divide fractions.
How To Divide Fractions
Before you start, look at both of your fractions, take a deep breath, and if a sixth grader can learn to divide fractions, you can master dividing fractions.
Dividing Fractions — Process & Examples
The first step in dividing fractions is as simple as that little pep talk. Let’s say you’re trying to find the answer to 2/3 ÷ 1/6. Do not do anything! Keep the numerator and denominator of both numbers as they are.
The second step in dividing fractions is to multiply the two fractions. So, you just need to change the division sign (÷) sign to the multiplication sign (x): 2/3 ÷ 1/6 becomes 2/3 x 1/6.
The third step in dividing fractions is to find the reciprocal of the divisor – but don’t panic! Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction.
This means that you flip the numerator (top number) and denominator (bottom number) of the fraction to the right of the division sign, called the denominator.

For example, if you’re dividing 2/3 by 1/6, you start by inverting the divisor: 2/3 x 6/1 = 12/3.
You can see that the fraction is no longer in proper fraction form, in which the numerator is smaller than the denominator; This is an unfair part.
Now all you have to do is simplify the fraction 12/3. You do this by finding the largest number that divides evenly into both the numerator and denominator, which, in this case, is 3, which means the fraction simplifies to 4/1, or simply 4. That is your final answer.
Dividing fractions by mixed numbers is a little different. You must first convert mixed fractions (fractions containing whole numbers) to improper fractions and then divide them the same way you would divide two fractions. Here’s an example: 3/4 ÷ 1 1/2.

So, the first step is to convert 1 1/2 into an improper fraction. 1 1/2 is the same as 3/2. Now, the problem can be solved as: 3/4 ÷ 3/2.
So, you just need to change the division sign (÷) to the multiplication sign (x): 3/4 ÷ 3/2 becomes 3/4 x 3/2.
Leave your first fraction as it is, but flip the second fraction, so that 3/4 x 3/2 becomes 3/4 x 2/3 = 6/12.
So, to divide a mixed number by a fraction, first convert the mixed number to an improper fraction and follow the steps shown above.
Dividing Fractions (year 6)
Now that we have all the basic terminology and some examples, it’s easy to divide fractions with different denominators. Dividing fractions can be really difficult for many students. It is difficult to imagine dividing a fraction into a set of other fractions. For dividing fractions, many students memorize the “keep-change-flip” algorithm without knowing why it works.
Without a conceptual understanding of fraction division, students get stuck when facing problems (especially word problems) where they have to divide by non-unit fractions such as 2/3 or 3/4, or problems with a denominator larger than . Dividend
In sixth grade, when students need to divide mixed numbers, they often rely heavily on the multi-step “keep-change-flip” method that is difficult to remember and understand.
You can help your students understand how to divide fractions by using fraction strips to move them around. Manipulatives and visual representations are evidence-based strategies that aid in learning new mathematics concepts. Fraction strips can help students not only understand the concept of dividing fractions, but also see virtually how to solve these problems without doing any calculations.

Collect materials and explore. Give each student or pair of students a set of different strips. Ask students to cut each strip into unit fractions (with a numerator of 1). For students who struggle with fine motor skills, consider cutting out a few sets in advance. You can also make some laminated or card stock sets for students.
After cutting each strip into unit fractions, have students reassemble each strip so they have a complete printable set. Give students a copy of the printable, or project an image of the printable so they have a visual model to refer to.
Once students have arranged all the strips, reintroduce the concept of the whole. Remind students that the visual representation of 1 and the term “whole” are often interchangeable when we talk about fractions. Say, “There is 1 complete piece at the top of our set.” Then, ask students what they notice about the stripes down the entire piece. An example model. You can say, “I see that each row in the different rows is the same size.” Ask students to share what they see with a partner. Then ask some students to share with the whole class. Remind students of previous lessons where they worked on dividing whole numbers by fractions.
1. Review dividing whole numbers by fractions. Ask students to place 1 full strip on top of their desk. Below that strip, ask students to match the required 1/4 strips to equal 1 full size. Write the equation 1÷1/4=4 on the board and ask students how they know it is true. Students should look at the strips in front of them to understand the answers.

Review all of the common ways students can explain their answers visually and verbally by providing the following examples:
2. Explain how to use fraction strips to divide a fraction by a different fraction. Use the “I do, we do, you do” model (also called a gradual release model of instruction) to guide students through the process of using the strips.
I do: Explain and model using strips. Say, “Now we can use the same strategy to solve division problems using two fractions. Let’s look at 1/2 ÷ 1/6. I’ll start with the 1/2 strip at the top like this . Next, below this, I will put 1/2 I will put as many 1/6 strips as possible to match the strip. We can see that one, two, three 1/6 to match the 1/2 strip The straps fit. So I can conclude he fits 1/2 ÷ 1/6 = 3, or 1/6 times 1/2 three times.”
We do: Mentor students by trying with you. Say, “Now let’s try it together. Start with 1/2 again. I’ll put 1/2 on top. You do the same.” Model putting 1/2 strip on top. “This time divide 1/2 by 1/8. Let’s put as many 1/8 strips as possible to match the 1/2 strip.” Model this and then move on to helping students who need assistance. Prompt students who are able to set it up correctly to write a division problem with a solution.

Once everyone is finished, discuss the answers as a class. Write part number sentences for students who did not get the correct answer. Describe the solution in several ways.
You will: Select three division problems using unit fractions for both the divisor and dividend. Tell students that they will do these themselves. Say, “Try the next several problems on your own or with a partner. Once you’ve organized your fractions using the strips, be sure to write a division sentence with your solution.” Provide guidance as needed. When checking-in, ask students to explain their solutions using the language discussed at the beginning of class, such as “____ groups of ____ fit into ____.”
Teaching Tip: Many students, including English language learners (ELLs) and students who struggle with expressive language, benefit from having sentence frames on their desks. Print a set of frames and place them in a dry-erase pocket so students can write down their answers each time.
3. Move on to practice more challenging problems. Again follow the “I do, we do, you do” model.

I say: “Let’s try some problems that are a little more challenging. It starts at 2/3 the time.” Ideal for them. Students should place two 1/3 strips on top of their desks. “I want you to divide 2/3 by 1/6.” Demonstrate how to line up the 1/6 strips down to the 2/3 until you match the whole. Count the number of strips used out loud as you show them. “So, 2/3 ÷ 1/6 = 4.”
We do: “Now, let’s do this next one together. Let’s try 3/4 ÷ 1/8. I’m going to use three 1/4 strips to show the 3/4 at the top. You can do this too Just do it.” Model with 3/4 on top.” This time, divide 3/4 by 1/8. Let’s put it this way
