# 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:

### 2 9/15 + 3 10/15 = 94/15 = 6 4/15 ≅ 6.2666667

The spelled result in words is ninety-four fifteenths (or six and four fifteenths).### How do we solve fractions step by step?

- Conversion a mixed number 2 9/15 to a improper fraction: 2 9/15 = 2 9/15 = 2 · 15 + 9/15 = 30 + 9/15 = 39/15

To find a new numerator:

a) Multiply the whole number 2 by the denominator 15. Whole number 2 equally 2 * 15/15 = 30/15

b) Add the answer from the previous step 30 to the numerator 9. New numerator is 30 + 9 = 39

c) Write a previous answer (new numerator 39) over the denominator 15.

Two and nine fifteenths is thirty-nine fifteenths. - Conversion a mixed number 3 10/15 to a improper fraction: 3 10/15 = 3 10/15 = 3 · 15 + 10/15 = 45 + 10/15 = 55/15

To find a new numerator:

a) Multiply the whole number 3 by the denominator 15. Whole number 3 equally 3 * 15/15 = 45/15

b) Add the answer from the previous step 45 to the numerator 10. New numerator is 45 + 10 = 55

c) Write a previous answer (new numerator 55) over the denominator 15.

Three and ten fifteenths is fifty-five fifteenths. - Add: 39/15 + 55/15 = 39 + 55/15 = 94/15

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(15, 15) = 15. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 15 × 15 = 225. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - thirty-nine fifteenths plus fifty-five fifteenths is ninety-four fifteenths.

### 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.
