#1**+1 **

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.
