Order Fractions from Least to Greatest – Free Fraction Ordering Tool

Q: How many fractions can I order at once?

You can enter 2 to 5 fractions. The first two are required, and the remaining three are optional.

Q: What method does this calculator use?

This tool uses the LCD (Lowest Common Denominator) method. It finds the smallest number all denominators divide into evenly, converts each fraction to an equivalent fraction with that denominator, then compares the numerators to determine the order.

Q: What if two or more fractions are equal?

The tool recognizes equivalent fractions. For example, if you enter 2/3 and 4/6, the result will show them as equal (2/3 = 4/6) rather than placing one before the other.

Q: Does this tool work with negative fractions?

Yes. You can enter negative numbers for the numerator, and the tool will order them correctly on the number line.

Q: Can I use this for mixed numbers like 1 1/2?

Not directly. Convert mixed numbers to improper fractions first — for example, 1 1/2 becomes 3/2 — then enter them into the tool.

Q: Do I need to simplify my fractions before entering them?

No. The tool works with any fractions, whether simplified or not. It finds the LCD based on whatever denominators you enter.

Use this free order fractions calculator to sort fractions from least to greatest. Enter 2 to 5 fractions and get them arranged from smallest to largest with a clear, step-by-step explanation showing how the Lowest Common Denominator (LCD) is used to compare them.

Perfect for checking homework, studying for tests, or quickly comparing fractions. The tool finds the LCD, converts each fraction, and shows you exactly how the order is determined.

Example: Ordering 3 Fractions

Order $\frac{2}{5}$, $\frac{1}{3}$, and $\frac{3}{4}$ from least to greatest.

Step 1: Find the LCD of 5, 3, and 4. The LCD is 60

Step 2: Convert each fraction:

$\frac{2}{5} = \frac{24}{60}$, $\frac{1}{3} = \frac{20}{60}$, $\frac{3}{4} = \frac{45}{60}$

Step 3: Compare the numerators: 20 < 24 < 45

Step 4: Final order (least to greatest):

$\frac{1}{3} < \frac{2}{5} < \frac{3}{4}$
