Question

Which of the following is not the same as 0.00684 kg? 0.0684 dkg,6.84 g, 684 cg, 6,840 mg,

Answer 1

The Answer would be C.) 684 cg

Answer 2

Answer : 0.00684 kg is not equal to 0.0684 dkg.

Explanation :

The conversion used for mass from kilogram to dekagram is :

1 kg = 100 dkg

The conversion used for mass from kilogram to grams is :

1 kg = 1000 g

The conversion used for mass from kilogram to centigrams is :

1 kg = 100000 cg

The conversion used for mass from kilogram to milligrams is :

1 kg = 1000000 mg

Now we have to determine the same mass as 0.00684 kg.

(1) 1 kg = 100 dkg

0.00684 kg = $\frac{0.00684kg}{1kg}\times 100dkg=0.684dkg$

(2) 1 kg = 1000 g

0.00684 kg = $\frac{0.00684kg}{1kg}\times 1000g=6.84g$

(3) 1 kg = 100000 cg

0.00684 kg = $\frac{0.00684kg}{1kg}\times 100000cg=684cg$

(4) 1 kg = 1000000 mg

0.00684 kg = $\frac{0.00684kg}{1kg}\times 1000000mg=6840mg$

Hence, from this we conclude that, 0.00684 kg is not equal to 0.0684 dkg.
