Is this correct?

[matthewicee]

Are my answers right or is it in fraction.

 

[HallsofIvy]

Yes, that is correct. This is really just a matter of interpreting the diagram correctly. There is no indication whether the answers are to b given in decimal or fraction. Since the information is given in decimal, it would make sense to answer that way but I would not consider that required.

(What are they to be "committed" to?)

I too want to know what they are committed to!!
