Fraction calculator



This calculator multiplies fractions. Multiplies all numerators and places the result over the product of all denominators. Then simplify the result to the lowest terms or a mixed number.

The result:

2/3 * 3/4 = 1/2 = 0.5

Spelled result in words is one half.

How do we solve fractions step by step?

  1. Multiple: 2/3 * 3/4 = 2 · 3/3 · 4 = 6/12 = 1 · 6/2 · 6 = 1/2
    Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(6, 12) = 6. In the following intermediate step, cancel by a common factor of 6 gives 1/2.
    In other words - two thirds multiplied by three quarters is one half.

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.
