Answer: There are two distinct methods to achieve this.
Step-by-step explanation:
We know that we have
A total of rocks = 38
If we want to create groups of 10 or count them individually, there are two methods;
Case I:
When grouped into sets of 10
There will be four sets; the first set has 10 rocks,
The second set contains 10 rocks,
The third set also has 10 rocks,
And the fourth set will only have 8 rocks.
Case II:
If we group them individually,
There will be 38 separate sets.
