Jack did 3/5 of the problems on his weekend homework before Sunday. On Sunday, he solved 1/3 of what was left and the last 4 problems. How many problems were assigned for the weekend?

After doing \(\frac{3}{5}\) of his homework he has \(\frac{2}{5}\) left. 

 

Multiplying the \(\frac{2}{5}\) or his homework must be 6 questions. This is because \(1 - \frac{1}{3} = \frac{2}{3} = 4\), as your problem states "the last 4 questions". Thus, 1/3 is equal to 2 questions, and  \(\frac{2}{5}\) or his homework must be 6 questions. Multiply \(6 \cdot \frac{5}{2} = 15\)

 

Therefore, he was assigned 15 questions in total for the weekend.
