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:
131.88 * 24 = 79128/25 = 3165 3/25 = 3165.12
The result spelled out in words is seventy-nine thousand one hundred twenty-eight twenty-fifths (or three thousand one hundred sixty-five and three twenty-fifths).How do we solve fractions step by step?
- Conversion a decimal number to a fraction: 131.88 = 13188/100 = 3297/25
a) Write down the decimal 131.88 divided by 1: 131.88 = 131.88/1
b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)
131.88/1 = 1318.8/10 = 13188/100
Note: 13188/100 is called a decimal fraction.
c) Simplify and reduce the fraction
13188/100 = 3297 * 4/25 * 4 = 3297* 4/25* 4= 3297/25 - Multiple: 131.88 * 24 = 3297 · 24/25 · 1 = 79128/25
The second operand is an integer. It is equivalent to the fraction 24/1. Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(79128, 25) = 1. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words, three thousand two hundred ninety-seven twenty-fifths multiplied by twenty-four equals seventy-nine thousand one hundred twenty-eight twenty-fifths.
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.
