Fraction Calculator Operations
Working with fractions requires careful handling of numerators, denominators, and common factors. CalcSolver's fraction calculator performs addition, subtraction, multiplication, and division of fractions — automatically simplifying results to their lowest terms.
Adding fractions: 3/4 + 1/6 = 9/12 + 2/12 = 11/12. The key step is finding a common denominator (the LCD of 4 and 6 is 12). Multiplying fractions is simpler: 2/3 × 4/5 = 8/15 — multiply numerators together and denominators together, then simplify if possible.
Fraction operations are foundational for algebra, cooking measurements, and construction calculations. Mixed numbers (like 2½) must be converted to improper fractions (5/2) before calculations. Always check if results can be simplified — dividing both numerator and denominator by their greatest common factor. Use CalcSolver's percentage calculator and equation solver for related math tools.

Frequently Asked Questions
How do I add fractions with different denominators?
Find a common denominator by multiplying the denominators together (or finding the LCM), convert each fraction, then add the numerators. Example: 1/3 + 1/4 = 4/12 + 3/12 = 7/12.
How do I simplify a fraction?
Divide both numerator and denominator by their greatest common divisor (GCD). Example: 12/18 → GCD is 6 → 12÷6/18÷6 = 2/3.
How do I convert a fraction to a decimal?
Divide the numerator by the denominator. Example: 3/8 = 3 ÷ 8 = 0.375. Our calculator shows results in both fraction and decimal form.
How do I multiply and divide fractions?
Multiply: multiply numerators together and denominators together. Divide: flip the second fraction (reciprocal) and multiply. Example: 2/3 ÷ 4/5 = 2/3 × 5/4 = 10/12 = 5/6.
