Fraction calculator

This calculator adds two fractions. First, all fractions are converted to a common denominator when they have different denominators. To do this, find the Least Common Denominator (LCD) or multiply all denominators to determine a common denominator. Once all denominators are the same, add the numerators and place the result over the common denominator. Finally, simplify the result to its lowest terms or convert it to a mixed number.

The result:

1/3 + 1/6 = 1/2 = 0.5

The spelled result in words is one half.

How do we solve fractions step by step?

Add: 1/3 + 1/6 = 1 · 2/3 · 2 + 1/6 = 2/6 + 1/6 = 2 + 1/6 = 3/6 = 3 · 1/3 · 2 = 1/2
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(3, 6) = 6. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 3 × 6 = 18. In the following intermediate step, cancel by a common factor of 3 gives 1/2.
In other words - one third plus one sixth is one half.

Rules for expressions with fractions:

Fractions - write a forward slash to separate the numerator and 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 whole part and fraction and use a forward slash to input fraction i.e., 1 2/3 . A negative mixed fraction write for example as -5 1/2.
A slash is both a sign for fraction line and division, use a colon (:) for division fractions i.e., 1/2 : 1/3.
Decimals (decimal numbers) enter with a decimal dot . 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.
