Do you mean chapter 1 questions 5-9
Yes, that's right. In PracticeIt, the are listed as 1.5, 1.6, 1.7, 1.8, 1.9, under the "Chapter 1" heading.
It's important to notice that there are both "self-checks" and "exercises", so don't confuse "Self-Check 1.5" with "Exercise 1.5"!
Okay thank you very much
