# 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:

### 7 3/25 - 6 4/15 = 64/75 ≅ 0.8533333

Spelled result in words is sixty-four seventy-fifths.### How do we solve fractions step by step?

- Conversion a mixed number 7 3/25 to a improper fraction: 7 3/25 = 7 3/25 = 7 · 25 + 3/25 = 175 + 3/25 = 178/25

To find a new numerator:

a) Multiply the whole number 7 by the denominator 25. Whole number 7 equally 7 * 25/25 = 175/25

b) Add the answer from the previous step 175 to the numerator 3. New numerator is 175 + 3 = 178

c) Write a previous answer (new numerator 178) over the denominator 25.

Seven and three twenty-fifths is one hundred seventy-eight twenty-fifths. - Conversion a mixed number 6 4/15 to a improper fraction: 6 4/15 = 6 4/15 = 6 · 15 + 4/15 = 90 + 4/15 = 94/15

To find a new numerator:

a) Multiply the whole number 6 by the denominator 15. Whole number 6 equally 6 * 15/15 = 90/15

b) Add the answer from the previous step 90 to the numerator 4. New numerator is 90 + 4 = 94

c) Write a previous answer (new numerator 94) over the denominator 15.

Six and four fifteenths is ninety-four fifteenths. - Subtract: 178/25 - 94/15 = 178 · 3/25 · 3 - 94 · 5/15 · 5 = 534/75 - 470/75 = 534 - 470/75 = 64/75

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(25, 15) = 75. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 25 × 15 = 375. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - one hundred seventy-eight twenty-fifths minus ninety-four fifteenths is sixty-four seventy-fifths.

#### 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.
