Question

Which of the following is not the same as 2.97 milligrams? 0.0000297 kg, 0.00297 g, 0.297 ch

Answer 1

the correct answer its  0.002975

Answer 2

Answer:

              0.0000297 Kg is not the same as 2.97 mg.

Proof:

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.
