Thank you for the opportunity to help you with your question!

denote the numbers of answers for "no" as no, "not sure" as ns and "yes" as y, then we have

no+ns =370

y-no = 340

and

no+ns+y = 1000

y=1000-370 = 630

no = 630-340 = 290

ns = 370-290 = 80

percentage of respondents answered "yes," "no," and "not sure" are:

63%, 29% and 8% respectively

Please let me know if you need any clarification. I'm always happy to answer your questions.
