Understanding Fraction Operations (Formulas Explained)
To fully understand how the calculator works, let’s break down each operation.
1. Addition of Fractions
When adding fractions:
Formula:
ba+dc=bdad+bc
Explanation:
- Multiply numerator of first fraction by denominator of second
- Multiply numerator of second fraction by denominator of first
- Add both results
- Multiply denominators
2. Subtraction of Fractions
Formula:
ba−dc=bdad−bc
Explanation:
Same as addition, but subtract instead of adding numerators.
3. Multiplication of Fractions
Formula:
ba×dc=b×da×c
Explanation:
- Multiply numerators together
- Multiply denominators together
This is the simplest fraction operation.
4. Division of Fractions
Formula:
ba÷dc=b×ca×d
Explanation:
- Flip the second fraction
- Multiply normally
This is called “multiplying by the reciprocal.”
5. Fraction Simplification
After calculation, results are simplified using the Greatest Common Divisor (GCD).
Formula:
ba=b÷gcd(a,b)a÷gcd(a,b)
This ensures the fraction is in its simplest form.
6. Decimal Conversion
Formula:
Decimal=DenominatorNumerator
The calculator also converts final results into decimal format up to 4 decimal places.
Example Calculation
Let’s solve an example using the calculator.
Problem:
32+53
Step-by-Step:
| Step | Calculation |
|---|---|
| Multiply cross terms | (2 × 5) + (3 × 3) |
| Result numerator | 10 + 9 = 19 |
| Result denominator | 3 × 5 = 15 |
| Final fraction | 19/15 |
| Decimal value | 1.2667 |
Final Answer:
- Fraction: 19/15
- Decimal: 1.2667
Fraction Operation Comparison Table
| Operation | Formula Type | Example Result |
|---|---|---|
| Addition (+) | Cross multiplication | 19/15 |
| Subtraction (−) | Cross multiplication | 1/5 |
| Multiplication (×) | Direct multiplication | 6/15 |
| Division (÷) | Reciprocal multiplication | 10/9 |
