    FAQ

    Which modes are included in this solver?

    The solver covers nine workflows: ratio simplification (with equivalent ratio generation), a:b=c:d proportions, part–whole–percent conversions, direct and inverse proportion, ratio splitting with optional integer rounding, percent change and reverse percent, percent comparisons highlighting percentage points versus relative change, and map scale conversions.

    How do teacher mode and sharing tools help classroom work?

    Teacher mode keeps the worked steps visible for projection or screenshots, LaTeX export supports formal notes, and the share button copies a URL with all inputs so students can revisit exactly the same example.
