Fraction calculator
This fraction calculator performs all fraction operations - addition, subtraction, multiplication, division and evaluates expressions with fractions. It also shows detailed step-by-step information.
The result:
2*(2/3 + 4/3 + 2) = 8/1 = 8
The result spelled out in words is eight.How do we solve fractions step by step?
- Add: 2/3 + 4/3 = 2 + 4/3 = 6/3 = 3 · 2/3 · 1 = 2
Both fractions have the same denominator, which is then the common denominator in the adding them. In the following intermediate step, cancel by a common factor of 3 gives 2/1.
In other words, two thirds plus four thirds equals two. - Add: the result of step No. 1 + 2 = 2 + 2 = 2/1 + 2/1 = 2 + 2/1 = 4/1 = 4
Both fractions have the same denominator, which is then the common denominator in the adding them.
In other words, two plus two equals four. - Multiple: 2 * the result of step No. 2 = 2 * 4 = 2 · 4/1 · 1 = 8/1 = 8
The first operand is an integer. It is equivalent to a fraction 2/1. Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(8, 1) = 1.
In other words, two multiplied by four equals eight.
Rules for expressions with fractions:
Fractions - write a forward slash to separate the numerator and the denominator, i.e., for five-hundredths, enter 5/100. If you use mixed numbers, leave a space between the whole and fraction parts.Mixed numerals (mixed numbers or fractions) - keep one space between the whole part and fraction and use a forward slash to input fraction i.e., 1 2/3 . A negative mixed fraction write for example as -5 1/2.
A slash is both a sign for fraction line and division, use a colon (:) for division fractions i.e., 1/2 : 1/3.
Decimals (decimal numbers) enter with a decimal dot . and they are automatically converted to fractions - i.e. 1.45.

The calculator follows well-known rules for the order of operations. The most common mnemonics for remembering this order are:
- PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
- BEDMAS: Brackets, Exponents, Division, Multiplication, Addition, Subtraction.
- BODMAS: Brackets, Order (or "Of"), Division, Multiplication, Addition, Subtraction.
- GEMDAS: Grouping symbols (brackets: (){}), Exponents, Multiplication, Division, Addition, Subtraction.
- MDAS: Multiplication and Division (same precedence), Addition and Subtraction (same precedence). MDAS is a subset of PEMDAS.
1. Multiplication/Division vs. Addition/Subtraction: Always perform multiplication and division *before* addition and subtraction.
2. Left-to-Right Rule: Operators with the same precedence (e.g., + and -, or * and /) must be evaluated from left to right.
