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.
1/5 * 2 = 2/ = 0.4Spelled result in words is two fifths.
How do we solve fractions step by step?
- Multiple: 1/ * 2 = 1 · 2/ = 2/
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(2, 5) = 1. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - one fifth multiplied by two is two fifths.
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.
