Betty has 165 classic g. i. joe dolls in her collection, and she’s feeling generous. if she gives 1/3 of them to her buddy james, how many does she have left?

It is immensely important to go through all the details given in the question. Based on those details the answer to the question can be deduced.
Number of G.I. Joe in Betty's collection = 165
Number of G.I. Joe dolls Betty gave to Joe = 165 * (1/3)
                                                                     = 55
Then the number of G.I. Joe dolls Betty have now = (165 - 55)
                                                                                = 110
The number of G.I. Joe dolls that were left with Betty after giving away 1/3 rd of the dolls was 110. I hope the answer is absolutely clear to you. In future you can always use this procedure for solving similar kinds of problems.
