C Correct answer
Explanation

We know that


$1$  $kg =1000$  $gm$


Given That, we have to convert  $23$ $kg$  $13$  $gm$  to  $grams$


$23$ $kg = 23 \times 1000$  $grams$

               $= 23000$  $grams$

$23$ $kg$  $13$  $gm$ $ = 23kg + 13gm$

                   $ = 23000gm + 13gm$
                   $ = 23,013   $    $   gm$

So, Option $C$ is correct

$90000 \ \text{mg}=$ _____ $\text{kg}$.

  1. $0.9$
  2. $0.09$
  3. $9$
  4. $90$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

$1 \ \text{ g} =1000\  \text{mg}$

$\Rightarrow 1 \  \text{mg}=.001 \ \text{ g}$
$\Rightarrow 90000 \ \text{mg}  =.0001\times90000=90 \ \text{ g}$
$1 \ \text{kg}=1000 \ \text{ g}$
$\Rightarrow 1 \ \text{g}=.001 \ \text{ kg}$
$\Rightarrow 90 \ \text{g} =90\times.001=.09 \ \text{ kg}$
Option B is correct
