Fractions are essential in everyday math, from recipes to measurements, but adding them manually can be tricky (especially with unlike denominators). Let our tool find the least common denominator (LCD), add numerators, and simplify automatically. Check out how to use it below.
What is an Adding Fractions Calculator?
An adding fractions calculator is a digital tool that performs fraction addition by aligning denominators, summing numerators, and reducing the result to its simplest form. It handles proper fractions (e.g., 1/2), improper (e.g., 3/2), and mixed numbers (e.g., 1 1/2).
Key applications include:
- School math homework and test prep.
- Real-life uses like cooking (e.g., adding 1/4 + 1/3 cup flour).
- Advanced topics in algebra or engineering.
Our version stands out with support for up to four fractions at once, visual step breakdowns, and conversion to decimals for verification.

How to Add Fractions Manually: Step-by-Step Guide
Follow these rules for same or different denominators:
- Same Denominators: Add numerators, keep denominator (e.g., 1/5 + 2/5 = 3/5).
- Different Denominators: Find LCD, convert each fraction, add numerators, simplify.
- Mixed Numbers: Convert to improper, add, then convert back if needed.
Example: Add 1/2 + 1/3.
Steps: LCD = 6; 1/2 = 3/6, 1/3 = 2/6; 3/6 + 2/6 = 5/6 (already simplified).
Adding Fractions Examples: Same, Different, and Mixed Denominators
Practice with these real scenarios using our tool:
Same Denominators
3/8 + 1/8 = 4/8 = 1/2 (simplifies by dividing by 4).
Different Denominators
2/3 + 3/4: LCD=12; 8/12 + 9/12 = 17/12 (improper; as mixed: 1 5/12).
Mixed Numbers
1 1/4 + 2 1/2: Convert to 5/4 + 5/2 = 5/4 + 10/4 = 15/4 = 3 3/4.
| Type | Fractions | LCD | Result (Simplified) | Decimal |
|---|---|---|---|---|
| Same Denominators | 1/6 + 2/6 | 6 | 3/6 = 1/2 | 0.5 |
| Different Denominators | 1/2 + 1/4 | 4 | 3/4 | 0.75 |
| Mixed Numbers | 1 1/3 + 2 1/6 | 6 | 3 1/2 | 3.5 |
| Improper | 5/3 + 3/2 | 6 | 19/6 = 3 1/6 | 3.1667 |
