Fraction calculator
This calculator performs basic and advanced fraction operations, expressions with fractions combined with integers, decimals, and mixed numbers. It also shows detailed stepbystep 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.

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(2, 6) = 2. In the following intermediate step, cancel by a common factor of 2 gives
1

.
In other words – one half multiplied by two thirds is one third.
Rules for expressions with fractions:
Fractions
– use a forward slash to divide the numerator by the denominator, i.e., for fivehundredths, 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.
Math Symbols
Symbol  Symbol name  Symbol Meaning  Example 

+  plus sign  addition  1/2 + 1/3

*  asterisk  multiplication  2/3 * 3/4 
×  times sign  multiplication  2/3 × 5/6 
:  division sign  division  1/2 : 3 
/  division slash  division  1/3 / 5 
:  colon  complex fraction  1/2 : 1/3 
^  caret  exponentiation / power  1/4^3

The calculator follows wellknown 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.
