what is the reciprocal of 3 5/7
3 5/7 = 26/7, so the reciprocal is 7/26
using mixed numbers like this is stupid, in my opinion. No one will ever ask such a question in a real problem. You will be asked to find reciprocals of fractions, integers, decimals, etc., but it makes little sense to ask for the reciprocal of a mixed number. Can't do it without changing it to a fraction or decimal first.
