1. What is Mixed Number Subtraction?

This calculator handles subtraction of an integer from a mixed number. A mixed number consists of a whole number and a proper fraction (where the numerator is less than the denominator).

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( a \) — Whole number part
• \( b \) — Numerator of the fraction
• \( c \) — Denominator of the fraction
• \( d \) — Integer to subtract

Note: This calculation only works when the whole number part (a) is greater than or equal to the integer being subtracted (d).

3. When to Use This Calculation

Applications: This type of calculation is commonly needed in measurements (like cooking, construction) where you need to subtract whole units from mixed measurements.

4. Using the Calculator

Instructions: Enter the whole number, numerator, and denominator for the mixed number, then enter the integer to subtract. The calculator will show both the direct result and simplified form if possible.

5. Frequently Asked Questions (FAQ)

Q1: What if the whole number is smaller than the integer being subtracted?
A: This calculator only handles cases where a ≥ d. For a < d, you would need to convert the mixed number to an improper fraction first.

Q2: Does the calculator simplify fractions?
A: Yes, it shows both the direct result and a simplified version if simplification is possible.

Q3: Can I use negative numbers?
A: The calculator only accepts positive numbers for all inputs.

Q4: What if my fraction is improper (numerator > denominator)?
A: The calculator expects proper fractions (numerator < denominator). For improper fractions, convert to a mixed number first.

Q5: Why does the denominator have to be at least 1?
A: Division by zero is undefined, so denominators must be positive integers.
