How do I enter a negative mixed number?
Separate the whole number and fraction with a space, for example -1 1/2. The minus sign applies to the entire value: -(1 + 1/2) = -3/2.
Examples: 3/4, 1 1/2, -2, 0.25
Denominators cannot be zero
Add, subtract, multiply, or divide fractions without converting them to rounded decimals first. Enter proper fractions, improper fractions, mixed numbers, integers, or finite decimals.
See how each answer is obtained: convert mixed numbers or decimals, use a common denominator or a reciprocal when needed, then simplify the result. Each input can contain up to 300 characters.
Use a slash for a fraction such as 7/8, a space for a mixed number such as 2 3/5, or enter an integer or finite decimal. A leading minus sign applies to the complete mixed number.
Addition and subtraction use a common denominator. Multiplication combines numerators and denominators, while division multiplies by the reciprocal and rejects a zero divisor. Every answer is normalized to a positive denominator.
Separate the whole number and fraction with a space, for example -1 1/2. The minus sign applies to the entire value: -(1 + 1/2) = -3/2.
The numerator and denominator are divided by their greatest common divisor. For example, 6/8 becomes 3/4 by dividing both by 2; a negative result keeps the minus sign in the numerator.
The fraction result is exact for the accepted inputs. The decimal display is rounded to at most 12 decimal places, so a repeating decimal such as 1/3 is shown approximately.
