The options are not given; however, the question can still be answered

Given

Required

Determine the smallest set of number that describes the given value

First, we need to simplify the given value

Divide the numerator and denominator by 6

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
