Formula for Adding Rational Numbers
To understand how the calculator works, let’s break down the formula.
Basic Formula:
If you have two fractions:
a/b + c/d
The formula becomes:
(a × d + b × c) / (b × d)
Step-by-Step Explanation:
- Multiply numerator of first fraction with denominator of second
- Multiply numerator of second fraction with denominator of first
- Add both results
- Multiply both denominators
- Simplify the fraction
- Convert into decimal
Simplification Using GCD
The calculator also simplifies the fraction using Greatest Common Divisor (GCD).
GCD Formula Idea:
The GCD of numerator and denominator is used to reduce the fraction to lowest terms.
Example of Adding Rational Numbers
Let’s understand with a real example:
Example:
Add:
2/3 + 1/4
Step 1: Apply formula
Numerator:
(2 × 4) + (1 × 3) = 8 + 3 = 11
Denominator:
3 × 4 = 12
So result = 11/12
Step 2: Simplify
11/12 is already in simplest form.
Step 3: Decimal conversion
11 ÷ 12 = 0.9167
Final Answer:
| Type | Result |
|---|---|
| Fraction | 11/12 |
| Decimal | 0.9167 |
More Examples of Adding Rationals
Example 1:
1/2 + 1/2
= (1×2 + 1×2) / (2×2)
= 4/4
= 1
Example 2:
3/5 + 2/5
Same denominator:
= 5/5
= 1
Example 3:
5/6 + 1/3
Convert:
1/3 = 2/6
Now:
5/6 + 2/6 = 7/6
Decimal = 1.1667

Understanding Rational Numbers
A rational number is any number that can be expressed as:
p/q, where:
- p = numerator
- q = denominator (not zero)
Examples of rational numbers:
- 1/2
- 3/4
- -5/6
- 7 (because 7 = 7/1)
Real-Life Importance of Adding Fractions
