ASo all units are multiplied together and kept.
BSo the largest unit is always on top.
CSo the numbers are as small as possible.
DSo the unwanted units appear in both a numerator and a denominator and cancel.

Question 8Select all that apply

Select ALL statements that are true about dimensional analysis:

Mark the box next to EVERY answer that is true. More than one is correct.

AThe given measurement is written as a fraction over 1.
BConversion ratios are arranged so unwanted units cancel.
COnly the unit that remains after cancelling appears in the answer.
DUnits may be ignored as long as the numbers are multiplied correctly.
EMore than one conversion ratio can be used in a single chain.
