# 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 informations.

## The result:

### 11/6 * 63/4 = 63/8 = 7 7/8 = 7.875

The spelled result in words is sixty-three eighths (or seven and seven eighths).

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

1. Conversion a mixed number 1 1/6 to a improper fraction: 1 1/6 = 1 1/6 = 1 · 6 + 1/6 = 6 + 1/6 = 7/6

To find a new numerator:
a) Multiply the whole number 1 by the denominator 6. Whole number 1 equally 1 * 6/6 = 6/6
b) Add the answer from the previous step 6 to the numerator 1. New numerator is 6 + 1 = 7
c) Write a previous answer (new numerator 7) over the denominator 6.

One and one sixth is seven sixths.
2. Conversion a mixed number 6 3/4 to a improper fraction: 6 3/4 = 6 3/4 = 6 · 4 + 3/4 = 24 + 3/4 = 27/4

To find a new numerator:
a) Multiply the whole number 6 by the denominator 4. Whole number 6 equally 6 * 4/4 = 24/4
b) Add the answer from the previous step 24 to the numerator 3. New numerator is 24 + 3 = 27
c) Write a previous answer (new numerator 27) over the denominator 4.

Six and three quarters is twenty-seven quarters.
3. Multiple: 7/6 * 27/4 = 7 · 27/6 · 4 = 189/24 = 63 · 3/8 · 3 = 63/8
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(189, 24) = 3. In the following intermediate step, cancel by a common factor of 3 gives 63/8.
In other words - seven sixths multiplied by twenty-seven quarters is sixty-three eighths.

### 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 sign 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 /) have the same priority and must be evaluated from left to right.
