Formula Used in Adding Fractions Calculator
To understand how this calculator works, let’s break down the mathematical formulas.
1. Fraction Addition Formula
To add two fractions:
Formula:
ba+dc=b×d(a×d)+(c×b)
Where:
- a = numerator of first fraction
- b = denominator of first fraction
- c = numerator of second fraction
- d = denominator of second fraction
2. Simplification Formula
After addition, the fraction is simplified using the Greatest Common Divisor (GCD).
Formula:
- Find GCD of numerator and denominator
- Divide both by GCD
dennum÷GCD
3. Decimal Conversion Formula
Formula:
Decimal=DenominatorNumerator
Step-by-Step Example of Adding Fractions
Let’s understand with a real example.
Example:
Add:
2/5 + 3/4
Step 1: Apply formula
(2×4)+(3×5)=8+15=23Denominator=5×4=20
So:23/20
Step 2: Simplify fraction
GCD of 23 and 20 = 1
So fraction remains:
23/20
Step 3: Convert to decimal
23÷20=1.15
Final Answer:
| Type | Result |
|---|---|
| Fraction | 23/20 |
| Decimal | 1.1500 |
More Examples of Fraction Addition
Example 1:
1/3 + 1/6
- Result = 3/6 + 1/6 = 4/6
- Simplified = 2/3
- Decimal = 0.6667
Example 2:
5/8 + 1/4
- Convert: 1/4 = 2/8
- Add: 5/8 + 2/8 = 7/8
- Decimal = 0.8750
Example 3:
7/10 + 2/5
- Convert: 2/5 = 4/10
- Add: 7/10 + 4/10 = 11/10
- Decimal = 1.1000
