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:

45.79/100 * 3429 = 15701391/10000 = 1570 1391/10000 = 1570.1391

The result spelled out in words is fifteen million seven hundred one thousand three hundred ninety-one over ten thousand (or one thousand five hundred seventy and one thousand three hundred ninety-one over ten thousand).

How do we solve fractions step by step?

Conversion a decimal number to a fraction: 45.79 = 4579/100 = 4579/100

a) Write down the decimal 45.79 divided by 1: 45.79 = 45.79/1
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.)
45.79/1 = 457.9/10 = 4579/100
Note: 4579/100 is called a decimal fraction.

c) Simplify and reduce the fraction
4579/100 = 4579 * 1/100 * 1 = 4579 * 1/100 * 1
Divide: 45.79 / 100 = 4579/100 · 1/100 = 4579 · 1/100 · 100 = 4579/10000
The second operand is an integer. It is equivalent to the fraction 100/1. Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 100/1 is 1/100) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words, four thousand five hundred seventy-nine one-hundredths divided by one hundred equals four thousand five hundred seventy-nine over ten thousand.
Multiple: the result of step No. 2 * 3429 = 4579/10000 * 3429 = 4579 · 3429/10000 · 1 = 15701391/10000
The second operand is an integer. It is equivalent to the fraction 3429/1. Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(15701391, 10000) = 1. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words, four thousand five hundred seventy-nine over ten thousand multiplied by three thousand four hundred twenty-nine equals fifteen million seven hundred one thousand three hundred ninety-one over ten thousand.

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.

Math Symbols

Symbol	Symbol name	Symbol Meaning	Example
+	plus sign	addition	1/2 + 1/3
-	minus sign	subtraction	1 1/2 - 2/3

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.

Important Notes:
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.
