# 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:

### 1 2/5 + 2 3/10 = 37/10 = 3 7/10 = 3.7

The spelled result in words is thirty-seven tenths (or three and seven tenths).### How do we solve fractions step by step?

- Conversion a mixed number 1 2/5 to a improper fraction: 1 2/5 = 1 2/5 = 1 · 5 + 2/5 = 5 + 2/5 = 7/5

To find a new numerator:

a) Multiply the whole number 1 by the denominator 5. Whole number 1 equally 1 * 5/5 = 5/5

b) Add the answer from the previous step 5 to the numerator 2. New numerator is 5 + 2 = 7

c) Write a previous answer (new numerator 7) over the denominator 5.

One and two fifths is seven fifths. - Conversion a mixed number 2 3/10 to a improper fraction: 2 3/10 = 2 3/10 = 2 · 10 + 3/10 = 20 + 3/10 = 23/10

To find a new numerator:

a) Multiply the whole number 2 by the denominator 10. Whole number 2 equally 2 * 10/10 = 20/10

b) Add the answer from the previous step 20 to the numerator 3. New numerator is 20 + 3 = 23

c) Write a previous answer (new numerator 23) over the denominator 10.

Two and three tenths is twenty-three tenths. - Add: 7/5 + 23/10 = 7 · 2/5 · 2 + 23/10 = 14/10 + 23/10 = 14 + 23/10 = 37/10

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(5, 10) = 10. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 10 = 50. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - seven fifths plus twenty-three tenths is thirty-seven tenths.

### 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.
