From: | To: |
Multiplying a fraction by a whole number is a fundamental arithmetic operation that scales the fraction by the whole number. The operation follows the simple rule: multiply the numerator by the whole number while keeping the denominator the same.
The calculator uses the fraction multiplication formula:
Where:
Explanation: The calculator multiplies the numerator by the whole number and keeps the denominator the same, then simplifies the resulting fraction if possible.
Details: This operation is essential in scaling recipes, calculating proportions, solving algebraic equations, and many real-world applications involving ratios and scaling.
Tips: Enter the numerator and denominator of your fraction (denominator must be greater than zero), and the whole number you want to multiply by. The calculator will show the result in fraction form and simplified form if possible.
Q1: What if my denominator is zero?
A: The denominator cannot be zero in a fraction. The calculator will only accept denominators greater than zero.
Q2: How does the simplification work?
A: The calculator finds the greatest common divisor (GCD) of the numerator and denominator, then divides both by this number to simplify the fraction.
Q3: What if the result is a whole number?
A: The calculator will display the result as a whole number when the denominator simplifies to 1.
Q4: Can I multiply a whole number by a fraction?
A: Yes, multiplication is commutative, so \( c \times \frac{a}{b} \) gives the same result as \( \frac{a}{b} \times c \).
Q5: What about mixed numbers?
A: For mixed numbers, first convert them to improper fractions before using this calculator.
