Fraction Reciprocal Formula:
From: | To: |
The reciprocal of a fraction is obtained by interchanging the numerator and denominator. For any non-zero fraction a/b, its reciprocal is b/a. The product of a fraction and its reciprocal is always 1.
The calculator uses the reciprocal formula:
Where:
Explanation: The calculator first swaps the numerator and denominator, then simplifies the resulting fraction to its lowest terms.
Details: Reciprocals are fundamental in mathematics, especially in division of fractions, solving equations, and working with rational expressions. They are essential in algebra, calculus, and many real-world applications.
Tips: Enter any non-zero numerator and denominator. The calculator will show the reciprocal in both fractional and decimal form. The fraction will be simplified to its lowest terms.
Q1: What's the reciprocal of a whole number?
A: For any whole number n, the reciprocal is 1/n. For example, the reciprocal of 5 is 1/5.
Q2: What's the reciprocal of zero?
A: Zero has no reciprocal because division by zero is undefined.
Q3: What's the reciprocal of a mixed number?
A: First convert the mixed number to an improper fraction, then find its reciprocal.
Q4: How are reciprocals used in division?
A: Dividing by a fraction is the same as multiplying by its reciprocal (a/b ÷ c/d = a/b × d/c).
Q5: What's the reciprocal of a reciprocal?
A: The reciprocal of a reciprocal gives you back the original number (1/(1/x) = x).
