How to Order Fractions, Integers, and Mixed Numbers

When comparing fractions, it’s not enough to just look at numerators and denominators — they need to be on equal footing. To make a fair comparison, every number must be rewritten as a fraction with the same denominator.

Here’s the step-by-step method used by the calculator:

1. Convert integers and mixed numbers to improper fractions.
   Example:
   2 → 2/1
   3 5/8 → (3 × 8 + 5)/8 = 29/8
2. Find the least common denominator (LCD).
   This is the smallest number divisible by all denominators. You can find it manually or use an online LCD calculator to save time.
3. Rewrite each fraction with the LCD.
   Multiply numerators and denominators to get equivalent fractions with the same denominator.
4. Compare numerators.
   Once denominators match, simply compare numerators to determine which fractions are larger or smaller.
5. Reorder them.
   Arrange from least to greatest (ascending) or greatest to least (descending), depending on your goal.

Example: Ordering Fractions Step by Step

Let’s use an example from the calculator’s default input:

Input: 2, 3/4, 9/12, 3 5/8, -12/16
Order: from least to greatest

Step 1: Convert to improper fractions.
• 2 = 2/1
• 3/4, 9/12, and -12/16 stay the same
• 3 5/8 = 29/8

Step 2: Find the LCD of 1, 4, 8, 12, and 16 → LCD = 48

Step 3: Rewrite each using the LCD.
2 = 96/48
3/4 = 36/48
9/12 = 36/48
29/8 = 174/48
-12/16 = -36/48

Step 4: Compare numerators.
-36/48 < 36/48 = 36/48 < 96/48 < 174/48

Step 5: Restore to original form.
Final Order: -12/16 < 3/4 = 9/12 < 2 < 3 5/8

Ordering Fractions Calculator with Whole Numbers

This calculator isn’t limited to simple fractions — it can handle whole numbers, decimals, and mixed fractions together. You can input numbers like 4, 2/3, and 5.75, and the calculator will automatically convert them to fraction form for comparison.

How to Order Fractions with Different Denominators

Ordering fractions with unlike denominators might seem tricky, but the logic stays consistent: bring them to the same base.

Formula:

Equivalent Fraction = (Numerator × LCD/Denominator) / LCD

For instance, ordering 1/3, 3/5, and 2/7 involves finding the LCD of 3, 5, and 7, which is 105. Then rewrite:

• 1/3 = 35/105
• 3/5 = 63/105
• 2/7 = 30/105

Now you can clearly see the order: 2/7 < 1/3 < 3/5.

This principle also applies to problems like “arrange the fractions in descending order 3/5, 4/7, 8/9, 9/11.” Converting each fraction to have a common denominator reveals their true order from greatest to least.

Least to Greatest Fractions Calculator

A least to greatest fractions calculator is simply another name for an ordering fractions calculator that sorts numbers in ascending order. It’s ideal for math students, teachers, or anyone dealing with fraction worksheets.

Ordering Fractions Examples and Worksheets

Ordering fractions often appears in worksheets or standardized math tests. For instance:

• Compare 7/8, 3/4, 5/6 → Convert all to have denominator 24: 21/24, 18/24, 20/24 → 3/4 < 5/6 < 7/8
• Compare -1/2, 1/3, -2/5 → Negative fractions always rank lower than positive ones.

If you’re practicing, you can use printable Ordering Fractions from Least to Greatest Worksheets to build intuition for how denominators affect size.
