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:
4 3/9 - 2 7/9 = 14/9 = 1 5/9 ≅ 1.5555556
The result spelled out in words is fourteen ninths (or one and five ninths).How do we solve fractions step by step?
- Conversion a mixed number 4 3/9 to a improper fraction: 4 3/9 = 4 3/9 = 4 · 9 + 3/9 = 36 + 3/9 = 39/9
To find a new numerator:
a) Multiply the whole number 4 by the denominator 9. Whole number 4 equally 4 * 9/9 = 36/9
b) Add the answer from the previous step 36 to the numerator 3. New numerator is 36 + 3 = 39
c) Write a previous answer (new numerator 39) over the denominator 9.
Four and three ninths is thirty-nine ninths. - Conversion a mixed number 2 7/9 to a improper fraction: 2 7/9 = 2 7/9 = 2 · 9 + 7/9 = 18 + 7/9 = 25/9
To find a new numerator:
a) Multiply the whole number 2 by the denominator 9. Whole number 2 equally 2 * 9/9 = 18/9
b) Add the answer from the previous step 18 to the numerator 7. New numerator is 18 + 7 = 25
c) Write a previous answer (new numerator 25) over the denominator 9.
Two and seven ninths is twenty-five ninths. - Subtract: 39/9 - 25/9 = 39 - 25/9 = 14/9
Both fractions have the same denominator, which is then the common denominator in the subtracting them. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words, thirty-nine ninths minus twenty-five ninths equals fourteen ninths.
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.
