Add, subtract, multiply, and divide fractions. Results are automatically simplified to the lowest terms and shown as both fraction and decimal.
a/b + c/d = (a×d + c×b) / (b×d). Then simplify by dividing by GCF. Example: 1/3 + 1/4 = (4+3)/12 = 7/12.
a/b − c/d = (a×d − c×b) / (b×d). Example: 3/4 − 1/3 = (9−4)/12 = 5/12.
a/b × c/d = (a×c) / (b×d). Example: 2/3 × 3/4 = 6/12 = 1/2.
a/b ÷ c/d = a/b × d/c = (a×d) / (b×c). Flip the second fraction and multiply. Example: 2/3 ÷ 4/5 = 2/3 × 5/4 = 10/12 = 5/6.
