Fraction calculator
This calculator multiply fractions. Simply multiplies all numerators and place the result over the product of all denominators. Then simplify the result to the lowest terms or a mixed number.
Result:
2/3 × 5/6 = 5/9 ≅ 0.5555556
Spelled result in words is five ninths.How do we solve fractions step by step?
- Multiple: 2/3 * 5/6 = 2 · 5/3 · 6 = 10/18 = 5 · 2/9 · 2 = 5/9
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(10, 18) = 2. In the following intermediate step, cancel by a common factor of 2 gives 5/9.
In other words - two thirds multiplied by five sixths is five ninths.
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.
