The equation x × y = 12 represents all possible factor pairs of the number 12. This includes both integer and fractional solutions that when multiplied together equal 12.
The calculator uses the simple equation:
Where:
Explanation: For any given x value (except 0), the calculator computes the corresponding y value that satisfies the equation x × y = 12.
Details: Understanding factor pairs is fundamental in mathematics, particularly in algebra, fractions, and number theory. It helps in simplifying fractions, finding common denominators, and solving equations.
Tips: Enter any non-zero value for x. The calculator will compute the corresponding y value that satisfies the equation x × y = 12. Both integer and fractional inputs are accepted.
Q1: What are the integer factor pairs of 12?
A: The integer factor pairs are: (1, 12), (2, 6), (3, 4), (4, 3), (6, 2), and (12, 1).
Q2: Can I use fractions as input?
A: Yes, the calculator accepts fractional inputs. For example, entering 0.5 for x will give y = 24.
Q3: What happens if I enter 0?
A: Division by zero is undefined, so x cannot be 0. The calculator requires a non-zero value.
Q4: Are negative numbers allowed?
A: Yes, negative numbers are allowed. For example, entering -3 will give y = -4, since (-3) × (-4) = 12.
Q5: How is this useful in real life?
A: This concept is used in various applications including scaling recipes, calculating ratios, determining dimensions in construction, and solving proportion problems.
