# 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:

### 11/12 + 5/3 + 1/4 = 17/6 = 2 5/6 ≅ 2.8333333

The spelled result in words is seventeen sixths (or two and five sixths).### How do we solve fractions step by step?

- Add: 11/12 + 5/3 = 11/12 + 5 · 4/3 · 4 = 11/12 + 20/12 = 11 + 20/12 = 31/12

It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(12, 3) = 12. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 12 × 3 = 36. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - eleven twelfths plus five thirds is thirty-one twelfths. - Add: the result of step No. 1 + 1/4 = 31/12 + 1/4 = 31/12 + 1 · 3/4 · 3 = 31/12 + 3/12 = 31 + 3/12 = 34/12 = 2 · 17/2 · 6 = 17/6

It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(12, 4) = 12. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 12 × 4 = 48. In the following intermediate step, cancel by a common factor of 2 gives 17/6.

In other words - thirty-one twelfths plus one quarter is seventeen sixths.

### 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.
