#### Answer

Yes, 100 kg is approximately 15 stone and 10 pounds.

#### Work Step by Step

If we use the conversion rate given in the exercise is:
$15\text{ st } 10\text{ lb}= 15\times 14 \text{ lb}+10 \text{ lb}=220 \text{ lb}$
Now we can convert from pounds to kilograms to check the equivalency, we have to consider the following conversion rate:
$ 2.20\text{ lb}\approx 1 \text{ kg}$
After dividing both sides by $2.20$ we get:
$1\text{ lb}\approx\frac{1}{2.20} \text{ kg} $
We multiply both sides by 220 in order to get the answer to the question:
$220 \text{ lb} \approx \frac{220}{2.20}\text{ kg}= 100 \text{ kg} $
Yes, 100 kg is approximately 15 stone and 10 pounds.
