1. **Stating the problem:** We need to find the least number of staff members required to mind all children in a crèche, given the maximum number of children one staff member can mind for different age groups. 2. **Understanding the data:** The table shows age groups and the maximum number of children one staff member can mind: - Age 0-1: max 3 children per staff - Age 1-2: max 5 children per staff - Age 2-3: max 6 children per staff - Age 3-6: max 8 children per staff 3. **Formula and approach:** To find the least number of staff members needed, we use: $$\text{Number of staff} = \left\lceil \frac{\text{Total children}}{\text{Max children per staff}} \right\rceil$$ where $\lceil x \rceil$ means rounding up to the nearest whole number. 4. **Important rule:** Since staff members cannot be fractional, always round up after division. 5. **Applying the formula:** Without the total number of children in each age group, we cannot calculate exact staff numbers. If you provide the number of children in each age group, we can compute the least number of staff members needed. 6. **Summary:** The key is dividing the number of children in each age group by the maximum children per staff for that group, then summing the rounded-up results to get the total staff needed. Since the total children count is missing, please provide it to proceed with calculations.
