Subtracting Fractions Calculator

The Subtracting Fractions Calculator helps you quickly subtract two or more fractions and get the correct result instantly. Instead of solving fraction subtraction manually, you can simply enter the numerator and denominator of each fraction and the calculator will automatically find the difference, simplify the fraction, and show the decimal value.

This tool is helpful for students, teachers, and anyone learning basic mathematics. It also shows step-by-step explanations and visual results, making it easier to understand how fraction subtraction works.

You can use this tool as a fraction subtraction calculator, subtract fractions online calculator, or fractions difference calculator. It works for fractions with both the same denominators and different denominators.

How to Subtract Fractions

There are two main cases when subtracting fractions:

1. Same Denominator

If fractions have the same denominator, subtract the numerators and keep the denominator the same.

\[ \frac{5}{7} - \frac{2}{7} = \frac{5-2}{7} = \frac{3}{7} \]

2. Different Denominators

When fractions have different denominators, find a common denominator before subtracting.

\[ \frac{3}{4} - \frac{1}{6} \] LCM(4,6)=12 \[ \frac{3}{4} = \frac{9}{12}, \quad \frac{1}{6} = \frac{2}{12} \] \[ \frac{9}{12} - \frac{2}{12} = \frac{7}{12} \]

Fraction Subtraction Formula

If denominators are different, use the following formula:

\[ \frac{a}{b} - \frac{c}{d} = \frac{ad - bc}{bd} \]

Where a and c are numerators and b and d are denominators.

Examples of Subtracting Fractions

Example 1

\[ \frac{7}{8} - \frac{3}{8} \] \[ \frac{7-3}{8} = \frac{4}{8} \] \[ \frac{4}{8} = \frac{1}{2} \]

Example 2

\[ \frac{5}{6} - \frac{1}{3} \] Convert to common denominator \[ \frac{1}{3} = \frac{2}{6} \] \[ \frac{5}{6} - \frac{2}{6} = \frac{3}{6} \] \[ \frac{3}{6} = \frac{1}{2} \]

Steps to Subtract Fractions with Different Denominators

Find the least common denominator (LCD).
Convert fractions into equivalent fractions.
Subtract the numerators.
Keep the common denominator.
Simplify the fraction if possible.
