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:
1 - 5/6 = 1/6 ≅ 0.1666667
The result spelled out in words is one sixth.How do we solve fractions step by step?
- Subtract: 1 - 5/6 = 1/1 - 5/6 = 1 · 6/1 · 6 - 5/6 = 6/6 - 5/6 = 6 - 5/6 = 1/6
It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(1, 6) = 6. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 1 × 6 = 6. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words, one minus five sixths equals one sixth.
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.
