Work out mixed number to improper fraction instantly with clear inputs, formula shown and shareable results.
A mixed number w p/q means w + p/q. Writing the whole part over the same denominator gives (w·q + p)/q, the improper form.
Mixed to improper
w p/q = (w·q + p) / q
(3 × 5 + 2)/5 = 17/5 = 3.4.
The minus applies to the whole mixed number, so −3 2/5 is −17/5, not −15/5 + 2/5.
