How to Use the Fraction Calculator

  1. Pick a mode tab above the calculator: Arithmetic (+, −, ×, ÷), Simplify / Reduce, Fraction ↔ Decimal, Equivalent Fractions, or Compare.
  2. Enter your fractions in the stacked numerator and denominator boxes, and tick "Include Whole Numbers" if you want to type mixed numbers like 1 ¾.
  3. Choose the operator (+, −, ×, ÷) between the fractions, and switch to "3 Fractions" if your expression has a third term.
  4. Press "Calculate Steps" to see the instant answer badge, then read the step-by-step working below, which shows the LCD setup, GCF reduction, mixed number, decimal, and percentage forms.
  5. Use the operation pills under the title (or the links below the guide) to open a dedicated page for a single skill, such as adding fractions, simplifying fractions, or comparing fractions.

How the Subtracting Fractions Calculator with Steps Method Works

To subtract fractions with different denominators, convert them to a common denominator using the LCD, subtract the numerators, and reduce to simplest form.

Core Formula:
\(\frac{a}{b} - \frac{c}{d} = \frac{a \cdot d - b \cdot c}{b \cdot d}\)

Key Rules & Steps:

  1. Identify the Least Common Denominator (LCD) of both fractions.
  2. Rewrite each fraction with the common denominator.
  3. Subtract the second numerator from the first numerator.
  4. Simplify the resulting fraction using the Greatest Common Factor (GCF).

Worked Practice Examples:

Problem: 5/6 - 1/4
Result: 7/12
LCD of 6 and 4 is 12. 5/6 = 10/12, 1/4 = 3/12. 10/12 - 3/12 = 7/12.

Frequently Asked Questions (FAQs)

How do you subtract fractions with different denominators?

Find the common denominator (LCD), adjust numerators accordingly, subtract the numerators, and simplify the resulting fraction.

Can the result of subtracting fractions be negative?

Yes, if the second fraction is greater than the first fraction, the numerator will be negative (e.g., 1/4 - 3/4 = -2/4 = -1/2).
