TIME, RUNNING, SHOPPING, AND QUICK MATH
Add, subtract, multiply, or divide two fractions and see the simplified fraction, decimal value, and mixed-number form.
Your result
Enter your values and select Calculate. Your result stays on this device.
Addition and subtraction use a common denominator; multiplication multiplies across; division multiplies by the reciprocal. The result is reduced by the greatest common divisor.
Numerators and denominators are whole numbers, and neither denominator can be zero.
This free fraction calculator targets the full arithmetic task rather than returning only a decimal. Enter two fractions, choose an operation, and compare the reduced fraction with its decimal and mixed-number forms.
Use case
Add, subtract, multiply, or divide two fractions and see the reduced result, decimal value, mixed-number form, and greatest-common-divisor check.
Solve and simplify fraction arithmetic while comparing improper-fraction, mixed-number, and decimal forms.
Build a reliable scenario
Fraction Calculator helps you check a specific everyday planning question with figures that apply to you. Add, subtract, multiply, or divide two fractions and see the simplified fraction, decimal value, and mixed-number form. Add, subtract, multiply, or divide two fractions and see the reduced result, decimal value, mixed-number form, and greatest-common-divisor check. Solve and simplify fraction arithmetic while comparing improper-fraction, mixed-number, and decimal forms. The page keeps the method and limits visible so the result can be understood, compared, and checked instead of treated as an unexplained answer.
Prepare First numerator, First denominator, Operation, Second numerator and Second denominator. Enter the numerator and nonzero denominator of the first fraction. Choose addition, subtraction, multiplication, or division. Enter the second fraction and calculate. Review the greatest-common-divisor reduction, decimal value, and mixed-number form. Keep units, dates, currency, and time periods consistent.
The stated method is: Addition and subtraction use a common denominator; multiplication multiplies across; division multiplies by the reciprocal. The result is reduced by the greatest common divisor. Change one assumption at a time to see which input drives the result, then compare scenarios on the same basis.
Numerators and denominators are whole numbers, and neither denominator can be zero. Check the input and rounding, then calculate again.
Method and update
Last reviewed: 2026-08-10. This tool performs the stated formula locally in your browser using the values you enter.
Create a common denominator, convert both numerators, add them, and reduce the result.
Multiply the first fraction by the reciprocal of the second fraction.
Yes. It divides numerator and denominator by their greatest common divisor.
