The image you provided contains a math problem with three tasks. Let's break down each part and solve them one by one.

### Problem 1:
**Given Expression: \( 4 \times (-3) \times (-5) \)**

This problem requires multiplying the numbers step by step:
1. Multiply \( 4 \times (-3) = -12 \).
2. Then multiply \( -12 \times (-5) \). Since multiplying two negative numbers gives a positive result, the final answer is:
   \[
   -12 \times (-5) = 60
   \]
   
**Answer:** \( 60 \)

### Problem 2:
**Given Problem:**
- The Barangay Basketball Boys team won 13 out of 20 games.

**Questions:**
1. **How many games did the team lose?**
   - Since they won 13 games out of 20, the number of games they lost is:
     \[
     20 - 13 = 7 \text{ games}
     \]
   
2. **What is the team's winning percentage?**
   - The winning percentage is calculated as follows:
     \[
     \text{Winning Percentage} = \left( \frac{\text{Number of Wins}}{\text{Total Games}} \right) \times 100
     \]
     Substituting the values:
     \[
     \left( \frac{13}{20} \right) \times 100 = 65\%
     \]

**Answers:**
1. The team lost 7 games.
2. The winning percentage is 65%.

### Problem 3:
**Questions:**
- What is 12% of 80?
- What is 90% of 100?
- 157 out of 175 is what percentage?

**Solutions:**

1. **12% of 80:**
   \[
   \text{Percentage of a number} = \left( \frac{\text{Percentage}}{100} \right) \times \text{Number}
   \]
   \[
   \left( \frac{12}{100} \right) \times 80 = 9.6
   \]
   **Answer:** \( 9.6 \)
   
2. **90% of 100:**
   \[
   \left( \frac{90}{100} \right) \times 100 = 90
   \]
   **Answer:** \( 90 \)
   
3. **157 out of 175 as a percentage:**
   \[
   \text{Percentage} = \left( \frac{157}{175} \right) \times 100 = 89.71\% \text{ (rounded to two decimal places)}
   \]
   
**Answer:** \( 89.71\% \)

---

### Summary:
- **Problem 1:** \( 60 \)
- **Problem 2:**
  1. 7 games lost.
  2. 65% winning percentage.
- **Problem 3:**
  1. \( 9.6 \)
  2. \( 90 \)
  3. \( 89.71\% \)
