Fraction Addition Formula:
From: | To: |
Three fraction addition involves finding a common denominator and then summing the numerators. The result is a new fraction that represents the sum of the three original fractions.
The calculator uses the following formula:
Where:
Explanation: The calculator finds a common denominator (the product of all denominators) and adjusts each numerator accordingly before summing them.
Details: Adding fractions is fundamental in mathematics, used in various fields including engineering, physics, and finance. It's essential for combining ratios or parts of wholes.
Tips: Enter all six values (three numerators and three denominators). Denominators must be positive integers. The calculator will provide both fractional and decimal results.
Q1: What if I get a negative result?
A: Negative results are valid and indicate the sum of the fractions is negative. Check your input values if this was unexpected.
Q2: Why does the denominator have to be positive?
A: In mathematics, division by zero is undefined and negative denominators are conventionally made positive by adjusting the numerator sign.
Q3: How is the simplified form calculated?
A: The calculator uses the greatest common divisor (GCD) to reduce the fraction to its simplest form.
Q4: Can I use decimal numbers?
A: The calculator accepts decimal inputs for numerators but requires integers for denominators.
Q5: What if my result is an improper fraction?
A: Improper fractions (where numerator > denominator) are valid results. You may convert to mixed numbers if desired.
