# 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:

### 5 5/7 * 3 1/8 = 125/7 = 17 6/7 ≅ 17.8571429

The spelled result in words is one hundred twenty-five sevenths (or seventeen and six sevenths).### How do we solve fractions step by step?

- Conversion a mixed number 5 5/7 to a improper fraction: 5 5/7 = 5 5/7 = 5 · 7 + 5/7 = 35 + 5/7 = 40/7

To find a new numerator:

a) Multiply the whole number 5 by the denominator 7. Whole number 5 equally 5 * 7/7 = 35/7

b) Add the answer from the previous step 35 to the numerator 5. New numerator is 35 + 5 = 40

c) Write a previous answer (new numerator 40) over the denominator 7.

Five and five sevenths is forty sevenths. - Conversion a mixed number 3 1/8 to a improper fraction: 3 1/8 = 3 1/8 = 3 · 8 + 1/8 = 24 + 1/8 = 25/8

To find a new numerator:

a) Multiply the whole number 3 by the denominator 8. Whole number 3 equally 3 * 8/8 = 24/8

b) Add the answer from the previous step 24 to the numerator 1. New numerator is 24 + 1 = 25

c) Write a previous answer (new numerator 25) over the denominator 8.

Three and one eighth is twenty-five eighths. - Multiple: 40/7 * 25/8 = 40 · 25/7 · 8 = 1000/56 = 125 · 8/7 · 8 = 125/7

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(1000, 56) = 8. In the following intermediate step, cancel by a common factor of 8 gives 125/7.

In other words - forty sevenths multiplied by twenty-five eighths is one hundred twenty-five sevenths.

### 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.
