Step-by-step
- 1Apply the operation rulea/b + c/d = (a·d + c·b)/(b·d) = (1·3 + 1·2)/(2·3) = (3 + 2)/6
- 2Unsimplified result= 5/6
- 3Find the GCDGCD(5, 6) = 1 (Euclid’s algorithm)
- 4Divide top and bottom5/6 = (5 ÷ 1) / (6 ÷ 1) = 5/6
- 5Convert to decimal5 ÷ 6 = 0.833333

Formula
a/b + c/d = (ad + cb)/bd · a/b − c/d = (ad − cb)/bd · a/b × c/d = ac/bd · a/b ÷ c/d = ad/bc
Pro tips
- • For addition and subtraction the denominators are cross-multiplied — this works even when they differ.
- • Dividing by a fraction means multiplying by its reciprocal: a/b ÷ c/d = a/b × d/c.
- • Always simplify at the end by dividing both parts by their GCD — the calculator does this automatically.
