The correct answer of the given question above would be option C. The measurement that is not the same as 2.97 milligrams is .00297. Here are the given conversions: 0.0000297 kg = 2.97 mg
0.297 cg = 2.97 mg
0.00297 cg = 0.0297 mg. For 1 mg = .1cg, .001g and 000001 kg. This gives us the answer which is C.

we have

\(2.97\ milligrams\)

case a) \(0.0000297\ kg\)

convert \(2.97\ milligrams\) to kg and compare

we know that

\(1\) mg is equal to \(1*10^{-6}\ kg\)

so

\(2.97*1*10^{-6}= 0.00000297\ kg\)

\(0.00000297\ kg eq0.0000297\ kg\)

case b) \(0.297\ cg\)

convert \(2.97\ milligrams\) to cg and compare

we know that

\(1\) mg is equal to \(0.1\ cg\)

so

\(2.97*0.1= 0.297\ cg\)

\(0.297\ cg=0.297\ cg\)

case c) \(0.00297\ cg\)

convert \(2.97\ milligrams\) to cg and compare

we know that

\(1\) mg is equal to \(0.1\ cg\)

so

\(2.97*0.1= 0.297\ cg\)

\(0.297\ cg eq0.00297\ cg\)

therefore

the answer is

\(0.0000297\ kg\)

\(0.00297\ cg\)
