Formula Used in Fraction Addition
To understand how the calculator works, let’s break down the mathematical formula.
Fraction Addition Formula:
If we have two fractions:
a/b + c/d
The formula is:
Step 1: Multiply cross terms
- (a × d) + (c × b)
Step 2: Multiply denominators
- b × d
Final Formula:
(a/b + c/d) = (ad + bc) / bd
Simplification Step
After addition, the result is simplified using the GCD (Greatest Common Divisor):
Simplification Formula:
- Divide numerator and denominator by GCD
Decimal Conversion Formula:
Decimal Value = Numerator ÷ Denominator
Example of Fraction Addition
Let’s understand with a real example.
Example:
Add:
3/4 + 2/5
Step 1: Apply Formula
Numerator:
- (3 × 5) + (2 × 4)
- 15 + 8 = 23
Denominator:
- 4 × 5 = 20
So:
Result = 23/20
Step 2: Simplify Fraction
23 and 20 have no common factor except 1, so it remains:
23/20
Step 3: Convert to Decimal
23 ÷ 20 = 1.1500
Final Answer:
| Type | Result |
|---|---|
| Fraction | 23/20 |
| Decimal | 1.1500 |
Fraction Addition Table (Quick Reference)
| Fraction 1 | Fraction 2 | Result (Fraction) | Decimal |
|---|---|---|---|
| 1/2 | 1/2 | 1/1 | 1.0000 |
| 1/3 | 1/6 | 1/2 | 0.5000 |
| 2/5 | 1/5 | 3/5 | 0.6000 |
| 3/4 | 1/4 | 1/1 | 1.0000 |
| 5/6 | 1/3 | 7/6 | 1.1667 |
Understanding Fraction Addition in Simple Words
When adding fractions, we cannot simply add numerators and denominators directly unless they are the same.
Example of Wrong Method:
❌ 1/2 + 1/3 = 2/5 (Incorrect)
Correct Method:
✔ 1/2 + 1/3 = 5/6
This is why finding a common denominator is important.
Our calculator automatically handles this step for you.
What Is GCD in Fraction Simplification?
GCD (Greatest Common Divisor) is the largest number that divides both numerator and denominator.
Example:
Fraction = 8/12
- GCD = 4
- Simplified = 2/3
This ensures the fraction is in its lowest form.
