- Numerator
- Denominator
Example: 1 ⅖
Step 3: Click Calculate
The calculator will:
- Convert both mixed numbers into improper fractions
- Find a common denominator
- Add the fractions
- Simplify the result
- Convert back to a mixed number
Step 4: View Result
The final answer is displayed in simplified mixed number form.
Formula for Adding Mixed Numbers
To understand how the calculator works, let’s break down the math behind it.
Step 1: Convert Mixed Numbers into Improper Fractions
Formula:
Improper Fraction = (Whole × Denominator + Numerator) / Denominator
Example:
2 ¾ = (2 × 4 + 3) / 4 = 11/4
Step 2: Find Common Denominator
For two fractions:
a/b + c/d
Common denominator = b × d
Step 3: Add Fractions
Formula:
(a × d + c × b) / (b × d)
Step 4: Simplify Fraction
Use GCD (Greatest Common Divisor):
Simplified fraction = numerator ÷ GCD / denominator ÷ GCD
Step 5: Convert Back to Mixed Number
Formula:
- Whole = numerator ÷ denominator
- Remainder = numerator % denominator
Final result:
Whole + remainder/denominator
Example of Adding Mixed Numbers
Let’s solve a real example step by step.
Example:
Add:
2 ¾ + 1 ⅖
Step 1: Convert to Improper Fractions
2 ¾ = (2 × 4 + 3) = 11/4
1 ⅖ = (1 × 5 + 2) = 7/5
Step 2: Find Common Denominator
4 × 5 = 20
Step 3: Convert Fractions
11/4 = 55/20
7/5 = 28/20
Step 4: Add Fractions
55 + 28 = 83/20
Step 5: Convert to Mixed Number
83 ÷ 20 = 4 remainder 3
Final answer:
4 3/20
Mixed Numbers Addition Table
| Mixed Numbers | Improper Fractions | Result |
|---|---|---|
| 1 ½ + 2 ½ | 3/2 + 5/2 | 4 |
| 2 ¾ + 1 ¼ | 11/4 + 5/4 | 4 |
| 3 ⅓ + 2 ⅔ | 10/3 + 8/3 | 6 |
| 4 ½ + 1 ½ | 9/2 + 3/2 | 6 |
| 5 ⅕ + 2 ⅕ | 26/5 + 11/5 | 7 2/5 |
