Here you will learn about ordering fractions from least to greatest and greatest to least.

Students will first learn about ordering fractions as part of numbers and operations of fractions in 4th grade.

**Ordering fractions** is arranging a set of fractions from least to greatest (**ascending **order) or from greatest to least (**descending** order).

To do this you rewrite the fractions so that they have common denominators and then compare the numerators.

For example,

If you order these fractions from least to greatest…

The order becomes…

You can prove this order is correct by creating common denominators. All the denominators (2, 4 and 8) have a common multiple of 8, so you can use 8 as the common denominator.

Now the equivalent fractions are: \; \cfrac{2}{8}, \cfrac{3}{8}, \cfrac{4}{8}, \cfrac{5}{8}, \cfrac{6}{8}.

Since the fractions have the same denominators all the parts are the same size. You can use the size of the numerators to order the fractions. The fractions are in order from least to greatest, because the numerators are in order from least to greatest.

How does this relate to 4th grade math?

**Grade 4: Numbers and Operations – Fractions (4.NF.A.2)**Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as \cfrac{1}{2}. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.

In order to order fractions:

**Create equivalent fractions that have a common denominator.****Order the fractions by the size of the numerator.****Rewrite the fractions in their original form.**

In order to order mixed numbers:

**Convert mixed numbers to improper fractions.****Create equivalent fractions that have a common denominator.****Order the fractions by the size of the numerator.****Rewrite the fractions in their original form.**

You can write all the numbers as fractions (proper and improper) or as mixed numbers. To use the same steps as above, write them all as fractions.

For 1\cfrac{1}{2}, break the whole into halves, then count the total halves.

There are 3 halves, so 1 \cfrac{1}{2} = \cfrac{3}{2}.

There are 5 thirds, so 1 \cfrac{2}{3} = \cfrac{5}{3}.

**Rewrite the fractions in their original form.**

- Before ordering multiple fractions, students should be comfortable comparing two fractions. Comparing fractions can be done through common numerators, common denominators or with benchmark fractions. Although not modeled here, these strategies can also be used for ordering fractions.

- Fraction work in 3rd grade centers around understanding through models; particularly area models and number lines. To build on this in 4th grade, always have physical or digital models available for students to use when necessary.

- While ordering fractions worksheets have their place, look for ways to incorporate real world activities as practice as well. For example, students can order the ingredients of a recipe or they can measure multiple items in inches and then order the measurements.

**Assuming that an improper fraction is smaller than a mixed number**

Both improper fractions and mixed numbers have wholes, they are just represented in different ways. Improper fractions include wholes as part of the numerator, so it is not always as obvious how many wholes there are. Because of this it can be easy to think that a mixed number is greater, but that is not always true.

For example,

\cfrac{8}{3} is larger than 2 \cfrac{1}{3}, because \cfrac{8}{3} = 2 \cfrac{2}{3}.

**Assuming the fraction with the smallest numbers is the smallest fraction**

It is the relationship between the numerator and denominator that matters, not just thinking about the numbers individually.

For example,

\cfrac{3}{4} may seem smaller than \cfrac{68}{100}, since 3 and 4 are smaller numbers, but if you use a common denominator to compare them, you see that \cfrac{3}{4} is the larger fraction:

\cfrac{3 \; \times \; 25}{4 \; \times \; 25}=\cfrac{75}{100} \; and \; \cfrac{75}{100}>\cfrac{68}{100}.

**Mixing up the order**

Pay attention to whether the order should be least to greatest or greatest to least. It is easy to confuse the two and often multiple choice tests have both orders listed as answers, but the correct answer is the order that was asked in the question.

**Not recording the answer as the original fractions**

It is easy to do the work and then forget to write the original numbers as your final answer.

For example,

Write these numbers in order of size:

\cfrac{5}{6} \quad \cfrac{7}{12} \quad \cfrac{3}{4}

With the same denominator:

\cfrac{10}{12} \quad \cfrac{7}{12} \quad \cfrac{9}{12}

In order of size:

\cfrac{7}{12} \quad \cfrac{9}{12} \quad \cfrac{10}{12}

The final answer is:

\cfrac{7}{12} \quad \cfrac{3}{4} \quad \cfrac{5}{6}

No, any other comparison strategy (like common numerators or using benchmark fractions) can be used with ordering. However, with four or more fractions, many people find it easiest to use common denominators to compare.

No, any common denominator can be used to order fractions, but using the least common denominator makes the calculations simpler.

While listing numbers is more common in elementary school, the comparison symbols can also be used to show order. For example, you could write the answer to #6 as 2 \cfrac{2}{3}>\cfrac{13}{5}>2 \cfrac{5}{12}>\cfrac{14}{6}.

Yes, but just as comparing fractions and mixed numbers requires some conversions other types of numbers may require conversions as well. It is important that you are seeing or thinking about numbers in the same form before comparing.
