Frequently Asked Questions about the Mixed Number Calculator
What is a mixed number?
A whole number combined with a proper fraction, such as 2 3/4. It equals the whole number plus the fraction, so 2 3/4 is 2 + 3/4, or 11/4 as an improper fraction.
How do I add mixed numbers?
Convert each mixed number to an improper fraction, find a common denominator, add the numerators, then simplify. For 2 3/4 + 1 1/2: 11/4 + 6/4 = 17/4 = 4 1/4.
How do I multiply mixed numbers?
Convert each mixed number to an improper fraction, multiply the numerators, multiply the denominators, then simplify. For 2 1/2 times 2: 5/2 times 2/1 = 10/2 = 5.
How do I divide mixed numbers?
Convert each mixed number to an improper fraction, then multiply the first by the reciprocal of the second. For 1 1/2 divided by 1/2: 3/2 times 2/1 = 6/2 = 3.
How do negative mixed numbers work?
The minus sign applies to the whole expression. -2 3/4 means -(2 + 3/4) = -11/4, not -2 + 3/4. Enter a negative whole number to flip the sign of the entire mixed number.
