To make the expression \(18 - 949 + 79 - 8\) easier to add, we should group it in a way that allows us to simplify or perform the calculations step by step.
Looking at the options provided, option **c. (18 − 8) − (9 4/9 + 7/9)** seems to be a promising choice. Here’s why:
1. **Grouping 18 and 8 together**: Simplifying \(18 - 8\) makes it straightforward.
2. **Recognizing that \(949\) can be expressed as \(9 + 4/9\)**: This allows you to manage the fractional part easier.
So, option c allows for simpler calculations.
Therefore, the best choice is:
**c.(18 − 8)−(9 4/9+7/9)**.
