Your first answer is right.

But the second problem has a similar flaw to the one we discussed a few minutes ago.

The problem ask us to find the number of starbursts Chad had left.

12 - (2 + 3) = 7 pieces left

None of your answer choices is correct.

12 - (2/12 + 3/12) = 12 - 5/12 = 11 7/12

So should I ask the teacher about the two problems that are faulty? But is A for the starburst question partly right? Is it just missing a few stuff like in the other question?

Yes, ask your teacher. None of the answers comes even close to answering the question.
