# 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:

### 11/12 + 5/3 + 1/4 = 17/6 = 2 5/6 ≅ 2.8333333

Spelled result in words is seventeen sixths (or two and five sixths).

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

1. Add: 11/12 + 5/3 = 11/12 + 5 · 4/3 · 4 = 11/12 + 20/12 = 11 + 20/12 = 31/12
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(12, 3) = 12. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 12 × 3 = 36. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - eleven twelfths plus five thirds is thirty-one twelfths.
2. Add: the result of step No. 1 + 1/4 = 31/12 + 1/4 = 31/12 + 1 · 3/4 · 3 = 31/12 + 3/12 = 31 + 3/12 = 34/12 = 2 · 17/2 · 6 = 17/6
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(12, 4) = 12. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 12 × 4 = 48. In the following intermediate step, cancel by a common factor of 2 gives 17/6.
In other words - thirty-one twelfths plus one quarter is seventeen sixths.

#### 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.
