1/2 ÷ 1/3 = 3/2.
Frequently asked questions
How do I use this calculator?
Enter numerator a, denominator b, numerator c, denominator d. The result updates automatically. Use Reset to restore the example values.
What method does it use?
(a/b)/(c/d) = ad/(bc). Exact signed-integer fraction arithmetic.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
