Explanation:
This is what happens when a volcano erupts.
To find the least degree of precision we swould
model it after the kg amount or 4.05 kg or two decimal places. So that would
add 0.56795 kg (0.57 kg) and then 0.1001 kg (0.1 kg) so that our answer would
be 4.72 kg.
<span>In the other hand, the greatest degree of
precision would be to conver 4.05 kg to 4050 g so that 4050g + 567.95 + 100.1
g= 4718.05 grams or 4718 g.</span>
