# Fraction calculator

This fraction calculator performs basic and advanced fraction operations, expressions with fractions combined with integers, decimals, and mixed numbers. It also shows detailed step-by-step information about the fraction calculation procedure. The calculator helps in finding value from multiple fractions operations. Solve problems with two, three, or more fractions and numbers in one expression.

## The result:

### 2 4/5 + 7 1/2 - 1 3/4 = 171/20 = 8 11/20 = 8.55

Spelled result in words is one hundred seventy-one twentieths (or eight and eleven twentieths).### How do we solve fractions step by step?

- Conversion a mixed number 2 4/5 to a improper fraction: 2 4/5 = 2 4/5 = 2 · 5 + 4/5 = 10 + 4/5 = 14/5

To find a new numerator:

a) Multiply the whole number 2 by the denominator 5. Whole number 2 equally 2 * 5/5 = 10/5

b) Add the answer from the previous step 10 to the numerator 4. New numerator is 10 + 4 = 14

c) Write a previous answer (new numerator 14) over the denominator 5.

Two and four fifths is fourteen fifths. - Conversion a mixed number 7 1/2 to a improper fraction: 7 1/2 = 7 1/2 = 7 · 2 + 1/2 = 14 + 1/2 = 15/2

To find a new numerator:

a) Multiply the whole number 7 by the denominator 2. Whole number 7 equally 7 * 2/2 = 14/2

b) Add the answer from the previous step 14 to the numerator 1. New numerator is 14 + 1 = 15

c) Write a previous answer (new numerator 15) over the denominator 2.

Seven and one half is fifteen halfs. - Add: 14/5 + 15/2 = 14 · 2/5 · 2 + 15 · 5/2 · 5 = 28/10 + 75/10 = 28 + 75/10 = 103/10

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, 2) = 10. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 2 = 10. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - fourteen fifths plus fifteen halfs is one hundred three tenths. - Conversion a mixed number 1 3/4 to a improper fraction: 1 3/4 = 1 3/4 = 1 · 4 + 3/4 = 4 + 3/4 = 7/4

To find a new numerator:

a) Multiply the whole number 1 by the denominator 4. Whole number 1 equally 1 * 4/4 = 4/4

b) Add the answer from the previous step 4 to the numerator 3. New numerator is 4 + 3 = 7

c) Write a previous answer (new numerator 7) over the denominator 4.

One and three quarters is seven quarters. - Subtract: the result of step No. 3 - 7/4 = 103/10 - 7/4 = 103 · 2/10 · 2 - 7 · 5/4 · 5 = 206/20 - 35/20 = 206 - 35/20 = 171/20

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, 4) = 20. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 10 × 4 = 40. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - one hundred three tenths minus seven quarters is one hundred seventy-one twentieths.

#### 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 evaluate from left to right.
