Improper fraction to mixed number formula
Divide the numerator by the denominator. The whole-number quotient becomes the whole part, and the remainder stays over the original denominator.
17 ÷ 5 = 3 with remainder 2.
Therefore, 17/5 = 3 2/5.
If the remainder and denominator share a common factor, reduce that fractional part to lowest terms.
Proper fractions and whole-number results
The converter also handles inputs that are already proper. For example, 3/5 remains 3/5. When the numerator divides evenly by the denominator, such as 18/6, the result is the whole number 3.
