Fractions — Math
This directory groups fractions tools within Math. A mathematical answer should be independent of your country. These tools cover arithmetic, algebra, geometry, fractions and statistics, along with financial mathematics that uses rates you enter yourself. Begin with the quantity you need to find, then check the required units and whether the formula assumes a particular timing convention. A loan-growth example using an entered rate is not a statement about a lender’s current offer.
Start with these tools
Complex Fraction Calculator
Divide one fraction by another and reduce the result to lowest terms.
Decimal to Fraction Calculator
Convert a terminating or repeating decimal approximation to a reduced fraction.
Decimal to Percent Calculator
Convert a decimal number to a percentage.
Estimating Sums and Differences of Fractions Calculator
Estimate a fraction sum or difference using benchmark fractions, and compare it with the exact result.
Fraction Calculator
Perform addition, subtraction, multiplication, and division with fractions.
For geometry, use the same length unit throughout an example. For statistics, distinguish a population from a sample and check how missing values are handled. Fraction and significant-figure tools answer different questions: an exact numerical value does not by itself tell you the precision of a measurement. The formula notes explain those distinctions. Work through a small example before trusting a large result, keep intermediate precision where possible, and round only for the intended presentation. Saved input links are convenient but are not private storage; anyone receiving a link can inspect the values it contains.
