Formula for Adding Fractions
To understand how the calculator works, let’s break down the mathematical formula.
Basic Formula:
For two fractions:
a/b + c/d
The formula is:(a×d+b×c)/(b×d)
Step-by-Step Explanation:
- Multiply numerator of first fraction by denominator of second
- Multiply numerator of second fraction by denominator of first
- Add both results
- Multiply both denominators
- Simplify the final fraction
Simplifying Fractions (Important Concept)
After adding fractions, the result is often not in simplest form. To simplify it:
We divide both numerator and denominator by their Greatest Common Divisor (GCD).
Example of Simplification:
Fraction: 8/12
- GCD of 8 and 12 = 4
- Divide both by 4
Result: 2/3
This is how the calculator automatically simplifies results.
Example of Fraction Addition
Example 1
Add:
1/2 + 1/4
Step-by-step:
Common denominator = 8
- (1 × 4) + (1 × 2) = 4 + 2 = 6
- Denominator = 2 × 4 = 8
Result:
6/8 → simplified = 3/4
Decimal:
0.75
Example 2
Add:
3/5 + 2/3
Calculation:
- (3 × 3) + (2 × 5) = 9 + 10 = 19
- Denominator = 5 × 3 = 15
Result:
19/15
Decimal:
1.2667
Example 3
Add:
5/8 + 1/8
Calculation:
Same denominator:
- 5 + 1 = 6
- Denominator = 8
Result:
6/8 → 3/4
Decimal:
0.75
