Fractions & Number Tools

Free browser-based fraction and number calculators for exact rational arithmetic, conversions, factors, divisibility, multiples, coprime checks, and prime numbers.

Represent → compare → factor → verify

Choose the representation first, compare or simplify equivalent values, then use factors, divisibility, multiples, GCF/LCM, or prime structure to verify the number relationship.

Divisibility Calculator is the dedicated tool for divisibility rules and remainder checks.

Fraction operations & simplification

Calculate, reduce, average, and work with mixed or complex fractions while keeping exact rational relationships visible.

Fraction CalculatorEnter fractions, mixed numbers, whole numbers, or finite decimals, choose an operation, and keep the exact reduced result connected to the wider fraction workflow.Mixed Number CalculatorEnter mixed numbers such as 2 1/3, fractions, whole numbers, or decimals and get an exact reduced result with a mixed-number form.Fraction SimplifierEnter any proper or improper fraction to reduce it, convert it to a mixed number, and inspect its decimal form.Fraction Average CalculatorPaste fractions, mixed numbers, whole numbers, or decimals to calculate the exact mean, mixed-number result, and decimal.Complex Fraction CalculatorEnter a numerator fraction and denominator fraction to simplify the complex fraction and see the reciprocal-multiplication step.Fraction of a Number CalculatorEnter a fraction or mixed number and a whole, decimal, or fractional value to calculate the exact product step by step.

Convert, compare & visualize

Move between fractions, decimals, percents, ratios, mixed forms, equivalent forms, LCD comparison, repeating decimals, and visual models.

Decimal to Fraction CalculatorEnter a decimal such as 0.75 to get the equivalent reduced fraction.Fraction to Decimal CalculatorEnter a numerator and denominator to calculate the decimal result.Fraction to Percent CalculatorEnter a numerator and denominator to calculate the equivalent percent.Percent to Fraction ConverterTurn integer or decimal percentages into exact reduced fractions and decimal values.Fraction to Ratio CalculatorEnter a rational value to see its reduced fraction, equivalent ratio, decimal value, and simplification step.Improper Fraction to Mixed Number ConverterEnter an improper fraction such as 16/3 to get the whole-number part, remainder, reduced fraction, and decimal value.Mixed Number to Improper Fraction ConverterEnter a mixed number such as 3 5/9 and convert it to a reduced improper fraction with the arithmetic shown.Comparing Fractions CalculatorEnter two rational values to see which is larger, a common-denominator comparison, and decimal equivalents.Least Common Denominator CalculatorPaste fractions to calculate the LCD and rewrite every fraction with that common denominator.Equivalent Fractions CalculatorEnter a rational value and generate a clean sequence of equivalent numerator/denominator pairs from its reduced form.Repeating Decimal to Fraction ConverterEnter values such as 0.(3), 0.1(6), or 12.34(56) and convert the repeating decimal to a reduced exact fraction.Fraction VisualizerEnter a fraction and render a browser SVG bar model with reduced fraction, mixed-number, decimal, and percent forms.

Factors, divisibility & division

Connect factors, GCF, LCM, common factors, coprime relationships, long division, and generated multiples.

Factor CalculatorEnter the supported integer to inspect its factors, then use the connected workflow when the task involves two or more numbers.GCF CalculatorEnter the supported integers to calculate the GCF and use the connected number workflow when you need the complete shared-factor list or a related divisibility check.LCM CalculatorEnter two or more whole numbers. Review the LCM, prime factorizations, the required highest prime powers, and the two-number identity LCM(a,b)×GCF(a,b)=|ab| where applicable.Common Factors CalculatorEnter two or more integers to list all positive common factors and the exact GCF in one browser-local calculation.Coprime CalculatorEnter two integers to calculate the GCF and determine whether their only positive common factor is 1.Long Division CalculatorEnter a dividend and divisor to get integer quotient, remainder, decimal result, and the identity dividend = divisor × quotient + remainder.Multiples CalculatorEnter a base integer, starting multiplier, and count to generate a copy-ready sequence of multiples locally.

Prime numbers

Check primality, factor integers into primes, or explore a bounded range of prime numbers.

Prime Number CheckerEnter an integer for the established primality check, then use the connected prime workflow for factorization or a list of primes in a range.Prime Factorization CalculatorEnter an integer from 2 to 10 trillion for responsive browser-side factorization. Review the exact prime powers, factor-pair context, divisor count, and factorization work.Prime Numbers in Range CalculatorEnter a range up to 200,000 integers wide with an endpoint no greater than 10,000,000 to find its primes locally.
