Hello,
If you're a student, please do the worksheets.
If you're a teacher, it's a good idea/practice to do the worksheet as if you were a student, before assigning it to find out if it's suitable and the answers are correct.
We make no comments about answers. There are way too many students looking for shortcuts. I hope you understand.
To the REST OF THE COMMUNITY, please don't post any answers.
