We explain what improper fractions and mixed numbers are and how the relationship between them can be taught to primary-school children. What are improper fractions and mixed numbers?A mixed number is made up of a whole number and a fraction. For example: An improper fraction is one that is 'top-heavy' so the numerator is bigger than the
denominator. For example: The relationship between mixed numbers and improper fractions can be best explained through the diagram above. These two shapes have been cut into four pieces. We can either express the amount of the shape we have as a mixed number: (1
3/4) or as an improper fraction (7/4). Working with mixed numbers and improper fractions in KS2In Years 5 and 6 children need to start to be able to see equivalence between mixed numbers and improper fractions. In the diagram above 8/3 is equivalent to 2 2/3. In the diagram above 10/3 is equivalent to 3 1/3. Converting improper fractions into mixed numbersWhat is 16/5 as a mixed number?
Converting mixed numbers into improper fractionsWhat is 2 7/8 as an improper fraction?
Improper Fractions to Mixed Numbers ConversionConverting improper fractions to mixed numbersHere, you can convert an improper fraction into mixed numbers. Enter the fraction numerator and denominator in the spaces above and press "To Mixed Numbers". You may enter values between -2147483648 and 2147483647. What is an improper fractionA fraction is improper when its numerator is greater than its denominator. When a fraction is 'improper' it can be expressed as a whole number plus a proper fraction. A proper fraction is a fraction that has a numerator smaller than its denominator, a fraction that has a value less than 1. The mixed numbers form shows the whole portion followed by the proper fraction. For example, 1.25 can be expressed as 5/4, or 1 and 1/4. 5/4 is an improper fraction, 1 1/4 is its mixed numbers representation. How to convert a fraction to mixed numbersThe fraction is first reduced to its lowest terms (see simplify fractions for more information). If the fraction's numerator is greater than the denominator (an improper fraction), then the whole portion is obtained by dividing the numerator by the denominator. The numerator of the proper fraction is the remainder of the division. The denominator is the same as the denominator of the original fraction. Download Article Download Article In math, improper fractions are fractions where the numerator (the top half) is a number that is bigger than or equal to the denominator (the bottom half). To convert an improper fraction to a mixed number (which is made from a fraction and a whole number, like 2 & 3/4), divide the numerator by the denominator. Write the whole number answer next to a fraction with the remainder in the numerator and the original denominator — you now have a mixed fraction!

Thanks for submitting a tip for review! Advertisement ReferencesAbout This ArticleArticle SummaryX To convert an improper fraction into a mixed number, start by writing the fraction as a division problem. Divide the numerator by the denominator. For instance, if the improper fraction is 7/5, write it out as 7 ÷ 5. Next, write out the whole number part of the answer. In our example, 5 divides into 7 one time, so the whole number is 1. This leaves us with a remainder of 2. The remainder will become the new numerator in the fraction, while the denominator remains the same. So, in the example of 7/5, you would get 7 ÷ 5 = 1 remainder 2. To express this as a fraction, write it as 1 and 2/5ths. If you want to turn it back into an improper fraction, multiply the whole number by the denominator and add the product to the numerator. The sum will become the new numerator in your improper fraction, while the denominator will remain the same.
