To find the range of a set of values, you need to subtract the smallest value from the largest value. In this case, the given values are 6, 10, 31/12, and 13.
1. First, identify the smallest and largest values:
- Smallest value: 6
- Largest value: 13
2. Next, calculate the range by subtracting the smallest value from the largest value:
13 - 6 = 7
3. Therefore, the range of the given values is 7.
Remember, when finding the range, you're looking for the difference between the highest and lowest values in the set.
