Answer:


= 17 (5)/(6)

Explanation:


23(1)/(2) + (-5(2)/(3))\\ \\ 23(1)/(2) = 23 + (1)/(2) = (46)/(2)+(1)/(2) = (46+1)/(2) = (47)/(2) = (141)/(6) \\ \\ 5(2)/(3) = 5 + (2)/(3) = (15)/(3) + (2)/(3) = (15+2)/(3) = (17)/(3) = (34)/(6)

Then:


23(1)/(2) + (-5(2)/(3)) = (141)/(6)+(-(34)/(6))\\ \\ = (141)/(6) - (34)/(6) = (141.34)/(6)\\ \\ = (107)/(6)


= (102)/(6) + (5)/(6) = 17 + (5)/(6)\\ \\ = 17 (5)/(6)
