Fraction Calculator
Work with mixed numbers, simplify fractions, and convert between fractions and decimals with clear step-by-step explanations.
Simplified Fraction
5/6
Mixed Number
5/6
Decimal
0.833333
Step-by-step solution
- Convert the mixed numbers to improper fractions: 1/2 = 1/2, 1/3 = 1/3.
- Find a common denominator and add numerators: (1×3) + (1×2) over 6.
- Raw result: 5/6.
- Simplify the fraction to 5/6.
EveryCalc calculators are designed for fast, practical estimates with transparent inputs and no required account. We use plain formulas, visible assumptions, and related tools so visitors can check the result from more than one angle.
Results are informational only. For financial, tax, legal, medical, construction, or other high-impact decisions, verify the output against primary sources or a qualified professional.

How this calculator works
What this page estimates
This Fraction Calculator is built to give a quick, browser-based estimate for fraction. Work with mixed numbers, simplify fractions, and convert between fractions and decimals with clear step-by-step explanations. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.
Calculation approach
The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For math & education tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.
Example workflow
For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.
Practical checks
- Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
- Run a low, base, and high case when the inputs are estimates.
- Check the related calculators below when the next decision depends on a different assumption.
How to interpret the fraction result
Best use
Use the result to learn a formula, check homework, verify a percentage, or understand the steps behind a number.
Cross-check
Compare the output with the method your class, textbook, spreadsheet, or teacher expects, especially when rounding rules are specified.
Watch for
A calculator can confirm arithmetic, but it cannot decide which formula a word problem requires. Read the setup before trusting the answer.
This page belongs to the Math & Education calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.
Before relying on this fraction estimate
Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.
Match the expected method
Teachers, textbooks, spreadsheets, and tests may require a specific formula, rounding rule, or notation format.
Inspect the setup
The calculator can check arithmetic, but the user still has to choose the right formula for the word problem or assignment.
Show the work when needed
Use the result to verify steps, then write out the method when an answer alone is not enough.
Rerun this page when the formula, rounding instruction, units, or assignment requirements change.
How to Use
- Choose a mode: arithmetic, simplify, decimal to fraction, or fraction to decimal.
- Enter your values. For arithmetic, you can use whole numbers plus numerators and denominators for mixed numbers.
- Pick an operation when solving arithmetic problems: add, subtract, multiply, or divide.
- Review the simplified fraction, mixed number, decimal output, and the worked steps below the calculator.
Frequently Asked Questions
How do you simplify a fraction?
Find the greatest common divisor of the numerator and denominator, then divide both by that number. The result is the fraction in lowest terms.
What is a mixed number?
A mixed number combines a whole number and a proper fraction, such as 2 1/3. It represents a value greater than one without using an improper fraction.
How do you convert a decimal to a fraction?
Write the decimal as a whole number over a power of 10, then simplify. For example, 0.75 becomes 75/100, which reduces to 3/4.
Why do fractions need a common denominator for addition and subtraction?
Fractions must represent equal-sized parts before you can combine them. A common denominator ensures both fractions are measured in the same unit.
How do you divide fractions?
Keep the first fraction, flip the second fraction, and multiply. This is often called multiplying by the reciprocal.
