Question

To properly record a measurements, you must record which of the following?
A. Inquiry
B. Unit
C. Number
D. Symbol
(please select all correct answers)

Answer 1

I'm not too sure about this but unit is definitely one of the answers. If "number" refers to (for example) the "6" in 6 inches then it should also count. I think "symbol" could also just be unit so I'm not sure about that.
