Question

Which of the following is not the same as 2.97 milligrams? A .0000297 kg B. .297 cg. C. .00297 cg

Answer 1

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`
