Fraction Calculator
Perform arithmetic operations on fractions with simplified results and decimal conversions.
How to Simplify
"Divide both top and bottom by their largest common factor." This keeps the ratio the same while making the numbers smaller and easier to handle.
Where to Use
Essential for recipes, woodworking, and early algebra where precise fraction models are preferred over decimals.
Precision
Fractions represent exact ratios. 1/3 is perfectly precise, whereas 0.333... is always an approximation.

See the Result
We'll instantly show you the final simplified fraction and its decimal value, along with a breakdown of how the math was done.
Practical Use Cases
Cooking and Baking
Scale your favorite recipes up or down without doing the messy mental math of 1/3 cups or 3/4 teaspoons.
DIY and Woodworking
Add up precise measurements like 5/8 and 3/16 inches to make sure every cut is perfect.
Early Algebra
Double-check your homework by seeing not just the final answer, but the step-by-step logic behind it.
Precision Design
Quickly convert exact fractional ratios into the precise decimals you need for CAD or 3D modeling.
FAQs
How do I interpret the simplified result?
The simplified result represents the fraction in its most basic form, where the numerator and denominator share no common factors other than 1. This is achieved by dividing both by their Greatest Common Divisor (GCD).
Why is the decimal value included?
Decimal values are useful for comparing fractions or using the result in digital contexts where fractions aren't supported. However, for 1/3, the decimal 0.333... is an approximation, while the fraction is exact.
