Since Anna is either grouping them as single rock or as group of 10, we need to find the maximum number of groups of 10 as follows: 38/10 = 3.8
This means that Anna can make maximum 3 groups of 10 rocks.
Based on this, the different ways to group the rocks are as follows:
- 3 groups of 10 and 8 (which are calculated as: 38-30) single rocks
- 2 groups of 10 and 18 (which are calculated as: 38-20) single rocks
- 1 group of 10 and 28 (which are calculated as: 38-10) single rocks
- 0 group of 10 and 38 (which are calculated as: 38-0) single rocks
<span>A. When adding two rational numbers a/b and c/d, the numerators a and c do not have to be integers. Therefore, the sum does not have to be a rational number. I think this is right might nor be :/

For 
to be conservative, we need to have
Integrate the first PDE with respect to 
:
Differentiate with respect to 
:
Now differentiate 
with respect to 
:
So we have
so is indeed conservative.
