# Fraction calculator

This fractions calculator performs all fraction operations - addition, subtraction, multiplication, division and evaluates expressions with fractions. It also shows detailed step-by-step informations.

## The result:

### 3 3/5 * 1 2/9 = 22/5 = 4 2/5 = 4.4

The spelled result in words is twenty-two fifths (or four and two fifths).### How do we solve fractions step by step?

- Conversion a mixed number 3 3/5 to a improper fraction: 3 3/5 = 3 3/5 = 3 · 5 + 3/5 = 15 + 3/5 = 18/5

To find a new numerator:

a) Multiply the whole number 3 by the denominator 5. Whole number 3 equally 3 * 5/5 = 15/5

b) Add the answer from the previous step 15 to the numerator 3. New numerator is 15 + 3 = 18

c) Write a previous answer (new numerator 18) over the denominator 5.

Three and three fifths is eighteen fifths. - Conversion a mixed number 1 2/9 to a improper fraction: 1 2/9 = 1 2/9 = 1 · 9 + 2/9 = 9 + 2/9 = 11/9

To find a new numerator:

a) Multiply the whole number 1 by the denominator 9. Whole number 1 equally 1 * 9/9 = 9/9

b) Add the answer from the previous step 9 to the numerator 2. New numerator is 9 + 2 = 11

c) Write a previous answer (new numerator 11) over the denominator 9.

One and two ninths is eleven ninths. - Multiple: 18/5 * 11/9 = 18 · 11/5 · 9 = 198/45 = 22 · 9/5 · 9 = 22/5

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(198, 45) = 9. In the following intermediate step, cancel by a common factor of 9 gives 22/5.

In other words - eighteen fifths multiplied by eleven ninths is twenty-two fifths.

### 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.
