#13: The arithmetic and the answer are correct.
I'm not sure how they're teaching it in school these days,
but I would prefer to see the problem written as 2.88 ÷ 6 .
#14: All correct. And notice that in this one, you did
write the problem in the opposite order, compared to #13.
Don't forget to write the unit "inches" with the answer.
#15: Good. (Copied 4.3 wrong. Minor.)
#16: Yep. Good.
Still no serious problems. It's really nice to see work like this.
