# 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:

### 8 6/10 - 4 7/12 = 241/60 = 4 1/60 ≅ 4.0166667

The spelled result in words is two hundred forty-one sixtieths (or four and one sixtieth).### How do we solve fractions step by step?

- Conversion a mixed number 8 6/10 to a improper fraction: 8 6/10 = 8 6/10 = 8 · 10 + 6/10 = 80 + 6/10 = 86/10

To find a new numerator:

a) Multiply the whole number 8 by the denominator 10. Whole number 8 equally 8 * 10/10 = 80/10

b) Add the answer from the previous step 80 to the numerator 6. New numerator is 80 + 6 = 86

c) Write a previous answer (new numerator 86) over the denominator 10.

Eight and six tenths is eighty-six tenths. - Conversion a mixed number 4 7/12 to a improper fraction: 4 7/12 = 4 7/12 = 4 · 12 + 7/12 = 48 + 7/12 = 55/12

To find a new numerator:

a) Multiply the whole number 4 by the denominator 12. Whole number 4 equally 4 * 12/12 = 48/12

b) Add the answer from the previous step 48 to the numerator 7. New numerator is 48 + 7 = 55

c) Write a previous answer (new numerator 55) over the denominator 12.

Four and seven twelfths is fifty-five twelfths. - Subtract: 86/10 - 55/12 = 86 · 6/10 · 6 - 55 · 5/12 · 5 = 516/60 - 275/60 = 516 - 275/60 = 241/60

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(10, 12) = 60. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 10 × 12 = 120. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - eighty-six tenths minus fifty-five twelfths is two hundred forty-one sixtieths.

### 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.
