Before Chad shared his starburst with his friends he had 12 pieces. He gave 2 orange ones to Katy and 2 green ones and a red one to BRett. Which expression can be used to find the number of starbursts that Chad had left?
A.12(2/12+3/12)
B.1(1/6+1/4)
C.1/6+1/4
D.2/12+3/12
A?

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.
