I think its b, but im really bad at math. can someone please help me out? I have to finish this by 12:15 so I can be on time to volunteer at the humane society. PLEASE HELP!

32 is not the LOWEST common denominator. Which other denominator is divisible by 2, 8, and 16?

ummmm 4?

Can you divide 4 by 8 or 16 and get a whole number?

no, it would be a decimal. im so confused. and im late! its not b, what is it?

16/16 = 1
16/8 = 2
16/4 = 4
The LCD is obviously 16.
Please learn your multiplication tables.
