About Mixed Number Arithmetic
A mixed number combines a whole number and a fraction, like 2 1/4. To perform arithmetic, mixed numbers are first converted to improper fractions. For 2 1/4, multiply the whole (2) by the denominator (4) and add the numerator (1) to get 9/4. After the operation, the result is converted back to a mixed number by dividing the numerator by the denominator.
Mixed numbers are common in cooking, construction, and everyday measurements where quantities fall between whole numbers. This calculator eliminates the manual conversion steps and gives you the answer in all three useful forms.
Frequently Asked Questions
How do you convert a mixed number to an improper fraction?
Multiply the whole number by the denominator, add the numerator, and place the result over the original denominator. For 3 2/5: (3 x 5) + 2 = 17, so the improper fraction is 17/5.
How do you add mixed numbers?
Convert both to improper fractions, find a common denominator, add the numerators, simplify, and convert back to a mixed number. This calculator does all those steps for you.
Can I use this for simple fractions without a whole number?
Yes. Leave the whole number field at 0 or empty, and the calculator treats it as a regular fraction. You can mix: one mixed number and one simple fraction, or two simple fractions.
