Fraction calculator
This fractions calculator performs all fraction operations - addition, subtraction, multiplication, division and evaluates expressions with fractions. It also shows detailed step-by-step information.
The result:
5/7 * 2/3 = 10/21 ≅ 0.4761905
The spelled result in words is ten twenty-firsts.How do we solve fractions step by step?
- Multiple: 5/7 * 2/3 = 5 · 2/7 · 3 = 10/21
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(10, 21) = 1. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - five sevenths multiplied by two thirds is ten twenty-firsts.
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.
