To represent \(-16 \div 8\), you can think of it using a number line or a set model that helps visualize division as repeated subtraction or partitioning.
-
Number Line Model: When you divide \(-16\) by \(8\), you are asking how many times \(8\) fits into \(-16\). Moving left on the number line (because you're dealing with negative numbers) in steps of \(8\):
- From \(0\), you would go left to \(-8\) (one step) and then another step to \(-16\) (two steps).
- This shows that \(-16\) divided by \(8\) gives you \(-2\).
-
Set Model: You can think of \(-16\) as representing a debt (or negative quantity) that needs to be shared among \(8\) groups. If you have \(-16\) items (debts) and you want to share them evenly among \(8\) groups, each group would end up with \(-2\) items (or debts).
In both cases, the result of \(-16 \div 8\) is \(-2\).
So, the representation you provided, \(-16 + 8 + 8 = -16 + (8) = 0\), does not precisely correlate to the division operation but could indicate that when adding together some positive numbers you could offset a negative result, but it doesn't clearly represent \(-16 \div 8\).
To summarize, the best way to represent \(-16 \div 8\) is via either of the models mentioned above, both leading to the conclusion that the result is \(-2\).
