# Fraction calculator

This calculator performs basic and advanced fraction operations, expressions with fractions combined with integers, decimals, and mixed numbers. It also shows detailed step-by-step information about the fraction calculation procedure. The calculator helps in finding value from multiple fractions operations. Solve problems with two, three, or more fractions and numbers in one expression.

## Result:

### 21/6 - 12/7 = 37/42 ≅ 0.8809524

Spelled result in words is thirty-seven forty-seconds.

### How do we solve fractions step by step?

1. Conversion a mixed number 2 1/6 to a improper fraction: 2 1/6 = 2 1/6 = 2 · 6 + 1/6 = 12 + 1/6 = 13/6

To find a new numerator:
a) Multiply the whole number 2 by the denominator 6. Whole number 2 equally 2 * 6/6 = 12/6
b) Add the answer from previous step 12 to the numerator 1. New numerator is 12 + 1 = 13
c) Write a previous answer (new numerator 13) over the denominator 6.

Two and one sixth is thirteen sixths
2. Conversion a mixed number 1 2/7 to a improper fraction: 1 2/7 = 1 2/7 = 1 · 7 + 2/7 = 7 + 2/7 = 9/7

To find a new numerator:
a) Multiply the whole number 1 by the denominator 7. Whole number 1 equally 1 * 7/7 = 7/7
b) Add the answer from previous step 7 to the numerator 2. New numerator is 7 + 2 = 9
c) Write a previous answer (new numerator 9) over the denominator 7.

One and two sevenths is nine sevenths
3. Subtract: 13/6 - 9/7 = 13 · 7/6 · 7 - 9 · 6/7 · 6 = 91/42 - 54/42 = 91 - 54/42 = 37/42
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(6, 7) = 42. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 7 = 42. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - thirteen sixths minus nine sevenths is thirty-seven forty-seconds.

#### Rules for expressions with fractions:

Fractions - use a forward slash to divide the numerator by 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 integer and
fraction and use a forward slash to input fractions i.e., 1 2/3 . An example of a negative mixed fraction: -5 1/2.
Because slash is both signs for fraction line and division, use a colon (:) as the operator of division fractions i.e., 1/2 : 1/3.
Decimals (decimal numbers) enter with a decimal point . 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 of operations are:
PEMDAS - Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
BEDMAS - Brackets, Exponents, Division, Multiplication, Addition, Subtraction
BODMAS - Brackets, Of or Order, Division, Multiplication, Addition, Subtraction.
GEMDAS - Grouping Symbols - brackets (){}, Exponents, Multiplication, Division, Addition, Subtraction.
MDAS - Multiplication and Division have the same precedence over Addition and Subtraction. The MDAS rule is the order of operations part of the PEMDAS rule.
Be careful; always do multiplication and division before addition and subtraction. Some operators (+ and -) and (* and /) has the same priority and then must evaluate from left to right.
