1. **State the problem:** We need to find the least number of staff members required to mind all children in the creche based on the maximum number of children one staff member can mind for each age group. 2. **Given data:** - Number of children in each age group: 0–1: 6, 1–2: 10, 2–3: 19, 3–4: 3, 4–5: 5 - Maximum children per staff member: 0–1: 3, 1–2: 5, 2–3: 6, 3–6: 8 3. **Calculate staff needed for each age group:** - For 0–1 years: $$\frac{6}{3} = 2$$ staff members - For 1–2 years: $$\frac{10}{5} = 2$$ staff members - For 2–3 years: $$\frac{19}{6} = 3.166\ldots$$, round up to 4 staff members - For 3–6 years (combining 3–4 and 4–5): total children = 3 + 5 = 8 $$\frac{8}{8} = 1$$ staff member 4. **Sum total staff members:** $$2 + 2 + 4 + 1 = 9$$ staff members 5. **Final answer:** The least number of staff members needed is **9**.
