Answer 1

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.

Answer 2

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

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

$0.00000297\ kg\neq0.0000297\ kg$

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

$2.97*0.1= 0.297\ cg$

$0.297\ cg\neq0.00297\ cg$

therefore

the answer is

$0.0000297\ kg$

$0.00297\ cg$
