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:

0.9289 - 0.7493/1000 = 9281507/10000000 = 0.9281507

The result spelled out in words is nine million two hundred eighty-one thousand five hundred seven over ten million.

How do we solve fractions step by step?

Conversion a decimal number to a fraction: 0.7493 = 7493/10000 = 7493/10000

a) Write down the decimal 0.7493 divided by 1: 0.7493 = 0.7493/1
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.)
0.7493/1 = 7.493/10 = 74.93/100 = 749.3/1000 = 7493/10000
Note: 7493/10000 is called a decimal fraction.

c) Simplify and reduce the fraction
7493/10000 = 7493 * 1/10000 * 1 = 7493 * 1/10000 * 1
Divide: 0.7493 / 1000 = 7493/10000 · 1/1000 = 7493 · 1/10000 · 1000 = 7493/10000000
The second operand is an integer. It is equivalent to the fraction 1000/1. 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 1000/1 is 1/1000) 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, seven thousand four hundred ninety-three over ten thousand divided by one thousand equals seven thousand four hundred ninety-three over ten million.
Conversion a decimal number to a fraction: 0.9289 = 9289/10000 = 9289/10000

a) Write down the decimal 0.9289 divided by 1: 0.9289 = 0.9289/1
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.)
0.9289/1 = 9.289/10 = 92.89/100 = 928.9/1000 = 9289/10000
Note: 9289/10000 is called a decimal fraction.

c) Simplify and reduce the fraction
9289/10000 = 9289 * 1/10000 * 1 = 9289 * 1/10000 * 1
Subtract: 0.9289 - the result of step No. 2 = 0.9289 - 7493/10000000 = 9289/10000 - 7493/10000000 = 9289 · 1000/10000 · 1000 - 7493/10000000 = 9289000/10000000 - 7493/10000000 = 9289000 - 7493/10000000 = 9281507/10000000
It is suitable to adjust both fractions to a common (equal) denominator for subtracting fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(10000, 10000000) = 10000000. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 10000 × 10000000 = 100000000000. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words, nine thousand two hundred eighty-nine over ten thousand minus seven thousand four hundred ninety-three over ten million equals nine million two hundred eighty-one thousand five hundred seven over ten million.

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

Op	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.
