Result
Adding fractions: Find a common denominator, add the numerators, then simplify.
a/b + c/d = (a×d + c×b) / (b×d)
Subtracting fractions: Same as addition but subtract the numerators.
a/b - c/d = (a×d - c×b) / (b×d)
Multiplying fractions: Multiply numerators together and denominators together.
a/b × c/d = (a×c) / (b×d)
Dividing fractions: Flip the second fraction and multiply.
a/b ÷ c/d = (a×d) / (b×c)
After calculating, the result is simplified by dividing both numerator and denominator by their Greatest Common Divisor (GCD).
