# 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:

### 5 4/7 ÷ 2 10/21 = 9/4 = 2 1/4 = 2.25

The spelled result in words is nine quarters (or two and one quarter).### How do we solve fractions step by step?

- Conversion a mixed number 5 4/7 to a improper fraction: 5 4/7 = 5 4/7 = 5 · 7 + 4/7 = 35 + 4/7 = 39/7

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 4. New numerator is 35 + 4 = 39

c) Write a previous answer (new numerator 39) over the denominator 7.

Five and four sevenths is thirty-nine sevenths. - Conversion a mixed number 2 10/21 to a improper fraction: 2 10/21 = 2 10/21 = 2 · 21 + 10/21 = 42 + 10/21 = 52/21

To find a new numerator:

a) Multiply the whole number 2 by the denominator 21. Whole number 2 equally 2 * 21/21 = 42/21

b) Add the answer from the previous step 42 to the numerator 10. New numerator is 42 + 10 = 52

c) Write a previous answer (new numerator 52) over the denominator 21.

Two and ten twenty-firsts is fifty-two twenty-firsts. - Divide: 39/7 : 52/21 = 39/7 · 21/52 = 39 · 21/7 · 52 = 819/364 = 91 · 9 /91 · 4 = 9/4

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 52/21 is 21/52) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, cancel by a common factor of 91 gives 9/4.

In other words - thirty-nine sevenths divided by fifty-two twenty-firsts is nine quarters.

### 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.
