Scroll down to learn what a mixed number is. After you have found the mixed number definition, you can then read more about the operations you can do to mixed fractions. However, if this is the start of your journey into the world of fractions, the versatile fraction calculator is a must!

A mixed number, also called a mixed fraction, is one of the ways to represent a fraction. In mixed fractions, you have a whole number, and a proper fraction put together – and that's where the name comes from; you're actually mixing two types of numbers!
Examples of mixed fractions are:

🍰 1 whole cake and 4 slices out of 6 of another → $1\frac{4}{6}$

🍫 1 whole chocolate bar and an additional 3 rows out of 5→ $1\frac{3}{5}$

🍊 2 whole oranges and 5 segments out of 8 from one more → $2\frac{5}{8}$

There's also another representation that can show the same amount – an improper fraction. Look at the image again – what will happen if you add all equal slices together instead of taking the whole items separately?

That's how improper fractions work – they show how many parts you have, and they don't specify if you have whole items. It's still the same number, just written differently!

Now that you know the mixed number definition, read the section below on how to turn a fraction into a mixed number (and vice versa).

In this section, we'll show you how to convert between mixed numbers and improper fractions.

• Mixed number to an improper fraction, e.g. $3\frac{1}{4}$

  1. Multiply the whole number by the denominator: $3 \times 4 = 12$.

  2. Add the result to your numerator: $12 + 1 = 13$.

  3. That's your new numerator – write it on top of your denominator: $\frac{13}{4}$.

• Improper fraction to a mixed number, e.g. $\frac{17}{6}$

  1. Divide the numerator by the denominator (the top number by the bottom number): $17 / 6 = 2$ remainder $5$.

  2. Take the whole number from the division – it's the whole part of the mixed number: $2$.

  3. Find the fractional part: the remainder from the division is the new numerator, and the denominator stays the same as in the original fraction: $\frac{5}{6}$.

  4. Put two numbers together – that's your mixed number: $2\frac{5}{6}$.

Note that what we present here is just a condensed version of the step-by-step instructions – if you need a more thorough explanation, check out our dedicated improper fraction to mixed number calculator and mixed number to improper fraction calculator.

There are two popular ways of adding mixed numbers. Let's check it with the example of adding $2\frac{2}{5}$2 and $1\frac{1}{2}$.

Method 1: adding whole numbers and fractions separately

As the number is mixed, you can do the adding operation separately on the whole part and fractional part:

• At first, add whole numbers:

  $2 + 1 = 3$

• Next, add the two fractional parts. In our case, the fractions have uneven denominators, so you need to find their least common multiple:

  $\text{LCM}(2,5) = 10$

  $\frac{2}{5} + \frac{1}{2} = \frac{4}{10} + \frac{5}{10} = \frac{9}{10}$

• Put the two parts together:

  $3\frac{9}{10}$

For our example, that's all you need to do, but it may happen that adding fractions will result in an improper fraction – then, you'll need to change it into a mixed number. Take a look at an example – adding $2\frac{3}{5}$ and $1\frac{1}{2}$:

$2\frac{3}{5} + 1\frac{1}{2}$

$2 + 1 = 3$

$\frac{3}{5}+\frac{1}{2} = \frac{6}{10} + \frac{5}{10} = \frac{11}{10} = 1\frac{1}{10}$

So $3 + 1\frac{1}{10} = 4\frac{1}{10}$

Method 2: Converting mixed numbers to improper fractions

• Let's start by converting our mixed numbers to their equivalent improper fractions:

  $2\frac{2}{5} = \frac{12}{5}$

  $1\frac{1}{2} = \frac{3}{2}$

• Do the standard addition of fractions with uneven denominators:

  $\frac{12}{5} + \frac{3}{2} = \frac{24}{10} + \frac{15}{10} = \frac{39}{10}$

• Finally, convert your result back into a mixed number:

  $\frac{39}{10} = 3\frac{9}{10}$

In our mixed number calculator, we've implemented the latter method. Give it a go!

Subtracting mixed fractions is similar to adding mixed numbers: all in all, the only difference is the sign.

However, things may become a little bit more complicated in certain special cases: if the fractional part of the first mixed number is smaller than the fractional part of the second mixed fraction. In such a case, you should regroup the whole and fractional parts, which may be a bit confusing for some people (check how regrouping works with this Khan Academy video).

To avoid this problem, use the second method for subtracting mixed fractions – that is, changing your mixed fractions to improper fractions. This technique will ensure that the steps are the same, no matter what the fractions are.

To multiply two mixed numbers, you should again use the mixed number ↔ improper fraction conversion. Let's transform a multiplying mixed fractions concept into a word problem:

You're a big fan of pumpkin pie 🥧 If you could, you would eat a whole pie every day. Unfortunately, your mum doesn't let you (well, she knows what's good for your health, right? 💪). She imposed the rule that you can eat only one and a half pumpkin pies per week – and you can have an equal slice of the pie every day. The question is, how many pies would you eat in two weeks and five days – more or less than four?

Let's have a look at the step-by-step instruction and solution:

1. Change your mixed numbers to improper fractions:

   You can write one and a half pie as $1\frac{1}{2}$: $1\frac{1}{2} = \frac{3}{2}$,

   and two weeks and five days as $2\frac{5}{7}$: $2\frac{5}{7} = \frac{19}{7}$.

2. Multiply the numerator by the other numerator and the denominator by the other denominator:

   $\frac{3}{2} \times \frac{19}{7} = \frac{3\times 19}{2\times 7} = \frac{57}{14}$

3. Change the result into a mixed fraction:

   $\frac{57}{14} = 4\frac{1}{14}$

Ooops. That's more than four pies! Type the numbers into the mixed number calculator to verify the result.

We will explain division as quickly as possible – dividing mixed numbers is very similar to multiplying mixed fractions. Only one additional step is needed – to get the reciprocal of your second fraction (divisor). If you don't know what reciprocal means, its just flipping the fraction upside down. If you wanted to divide mixed numbers $1\frac{1}{2}$ and $2\frac{5}{7}$, you would:

1. Change the mixed numbers to improper fractions:

   $1\frac{1}{2} = \frac{3}{2}$, $2\frac{5}{7} = \frac{19}{7}$

2. Find the reciprocal of the second fraction: $\frac{19}{7} → \frac{7}{19}$

3. Multiply the fractions (the numerator by the other numerator and the denominator by the other denominator):

   $\frac{3}{2}\times \frac{7}{19} = \frac{(3\times 7)}{(2\times 19)} = \frac{21}{38}$

Ok, we have to confess – we're sometimes a bit lazy 🦥 And that's the case here: we don't want to repeat ourselves too much! Because why should we write the same thing again and again if we've already done it? 🤔 Check out our other awesome calculators and read the detailed explanations on the mixed number to decimal or decimal to mixed number conversions!
