Answer

To solve the problem, we need to analyze the information given about the kids and their preferences for basketball, football, and volleyball.

### Step-by-Step Solution:

1. **Identify the number of kids who like each sport:**
- Kids who like only basketball: **10**
- Kids who like only football: **25**
- Kids who like both volleyball and football: **10**
- Kids who like only volleyball: **5**

2. **Calculate the total number of kids who like football:**
- Kids who like only football: **25**
- Kids who like both volleyball and football: **10**
- Therefore, total kids who like football = 25 (only football) + 10 (both volleyball and football) = **35**

3. **Identify the number of kids who like only basketball:**
- Kids who like only basketball: **10**

4. **Set up the ratio of kids who like football to those who like only basketball:**
- Ratio = (Total kids who like football) : (Kids who like only basketball)
- Ratio = 35 : 10

5. **Simplify the ratio:**
- To simplify, divide both sides by 5:
- 35 ÷ 5 = 7
- 10 ÷ 5 = 2
- Therefore, the simplified ratio is **7 : 2**.

### Final Answer:
The ratio of kids who like football to those who like only basketball is **7 : 2**.
