Frequently Asked Questions
How do I add 1/3 + 1/6?
Common denominator 6: 2/6 + 1/6 = 3/6 = 1/2. The tool shows each step — convert, operate, simplify — so homework checks itself.
Does it simplify automatically?
Yes — every result reduces via GCD: 4/8 becomes 1/2. Unreduced answers mark homework wrong even when numerically right.
Can I see decimals too?
Yes — each result carries its decimal equivalent (1/3 ≈ 0.333). Use decimals for money math, fractions for exact recipe scaling.
