Given
![Value = (-18)/(6)](https://img.qammunity.org/2021/formulas/advanced-placement-ap/high-school/mnwhg9o8n9der44sz79ywcipbw6y6v0x9l.png)
Required
Determine the smallest set of number that describes the given value
![Value = (-18)/(6)](https://img.qammunity.org/2021/formulas/advanced-placement-ap/high-school/mnwhg9o8n9der44sz79ywcipbw6y6v0x9l.png)
First, we need to simplify the given value
Divide the numerator and denominator by 6
![Value = -3](https://img.qammunity.org/2021/formulas/advanced-placement-ap/high-school/yq687svez2kfx9mmsjr5ezxehetm91ys3m.png)
Comparing -3 to set of numbers such as integers, real numbers, irrational number, etc.
We can limit -3 to two categories of numbers which are: Real numbers and Integers
But the scope of real numbers is wider than integers;
Hence, the smallest set of number is integer
