# Fraction calculator

This 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.

## Result:

### 34/5 * 15/7 = 228/35 = 6 18/35 ≅ 6.5142857

Spelled result in words is two hundred twenty-eight thirty-fifths (or six and eighteen thirty-fifths).

### How do we solve fractions step by step?

1. Conversion a mixed number 3 4/5 to a improper fraction: 3 4/5 = 3 4/5 = 3 · 5 + 4/5 = 15 + 4/5 = 19/5

To find a new numerator:
a) Multiply the whole number 3 by the denominator 5. Whole number 3 equally 3 * 5/5 = 15/5
b) Add the answer from previous step 15 to the numerator 4. New numerator is 15 + 4 = 19
c) Write a previous answer (new numerator 19) over the denominator 5.

Three and four fifths is nineteen fifths
2. Conversion a mixed number 1 5/7 to a improper fraction: 1 5/7 = 1 5/7 = 1 · 7 + 5/7 = 7 + 5/7 = 12/7

To find a new numerator:
a) Multiply the whole number 1 by the denominator 7. Whole number 1 equally 1 * 7/7 = 7/7
b) Add the answer from previous step 7 to the numerator 5. New numerator is 7 + 5 = 12
c) Write a previous answer (new numerator 12) over the denominator 7.

One and five sevenths is twelve sevenths
3. Multiple: 19/5 * 12/7 = 19 · 12/5 · 7 = 228/35
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(228, 35) = 1. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - nineteen fifths multiplied by twelve sevenths is two hundred twenty-eight thirty-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 signs 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 /) has the same priority and then must evaluate from left to right.
