Use positive entry boxes and set the sign separately for cleaner conversions.
Example Data Table
| Input | Mixed Number | Improper Fraction | Decimal | Percent |
|---|---|---|---|---|
| 2 3/4 | 2 3/4 | 11/4 | 2.75 | 275% |
| 7/3 | 2 1/3 | 7/3 | 2.333333 | 233.333333% |
| 0.625 | 5/8 | 5/8 | 0.625 | 62.5% |
| -1 2/5 | -1 2/5 | -7/5 | -1.4 | -140% |
Formula Used
1) Mixed Number to Improper Fraction
Numerator = (Whole × Denominator) + Numerator
Apply the sign after building the numerator. Example: 2 3/4 becomes (2 × 4) + 3 = 11, so the result is 11/4.
2) Improper Fraction to Mixed Number
Whole = floor(|Numerator| ÷ Denominator)
Remainder = |Numerator| mod Denominator
The final mixed number is Whole and Remainder/Denominator with the original sign restored.
3) Decimal to Fraction
Fraction = Whole digits / 10decimal places
After forming the fraction, divide numerator and denominator by their greatest common divisor to simplify the result.
4) Percent and Reciprocal
Percent = Decimal × 100
Reciprocal = Denominator / Numerator, except when the value equals zero because zero has no reciprocal.

FAQs
1) What is a mixed number?
A mixed number combines a whole number and a proper fraction, such as 3 1/2. It is another way to write an improper fraction larger than one.
2) What does this converter calculate?
It converts between mixed numbers, simple fractions, improper fractions, and decimals. It also shows percent value, reciprocal, whole part, and fractional part.
3) Why should fractions be simplified?
Simplified fractions are easier to read, compare, and use in later calculations. They also help students and professionals avoid unnecessary complexity.
4) Can I enter negative values?
Yes. Use the Number Sign field to switch between positive and negative values. This keeps the entry boxes simple and avoids sign confusion.
5) Why is zero denominator not allowed?
Division by zero is undefined in mathematics. A fraction with denominator zero does not represent a valid numeric value, so the calculator blocks it.
6) Are decimal conversions exact?
Yes for the digits you enter. A terminating decimal like 0.625 converts exactly to 5/8. Repeating decimals need approximation unless entered as fractions.
7) What is the reciprocal used for?
The reciprocal is useful in division, ratio work, scaling, algebra, and dimensional analysis. It flips the numerator and denominator of a fraction.
8) Why does the graph show components?
The graph helps you visualize how much of the number comes from the whole part and how much comes from the fraction. That makes comparisons easier.
