Which of the following is not the same as 2.97 milligrams? 0.297 kg, 0.00297 g, 0.297 ch

              0.0000297 Kg is not the same as 2.97 mg.

Converting 2.97 mg into Kg:

As,

                             1 mg is equal to  =  1.0 × 10⁻⁶ Kg

So,

                        2.97 mg will be equal to  =  X Kg

Solving for X,

                      X =  (2.97 mg × 1.0 × 10⁻⁶ Kg) ÷ 1 mg

                      X =  2.97 × 10⁻⁶ Kg

Or,

                      X =  0.00000297 Kg

Hence, 0.0000297 Kg is not the same.

Converting 2.97 mg into g:

As,

                             1 mg is equal to  =  0.001 g

So,

                        2.97 mg will be equal to  =  X g

Solving for X,

                      X =  (2.97 mg × 0.001 g) ÷ 1 mg

                      X =  0.00297 g

Hence, 0.00297 g is the same.

Converting 2.97 mg into cg:

As,

                             1 mg is equal to  =  0.10 cg

So,

                        2.97 mg will be equal to  =  X cg

Solving for X,

                      X =  (2.97 mg × 0.10 cg) ÷ 1 mg

                      X =  0.297 cg

Hence, 0.297 cg is the same.
