Let's solve the problems in your image step by step. I will start with the calculations and provide explanations:

### 1) \( 2.87 \times 9 \)
   - Perform the multiplication: 
     \[
     2.87 \times 9 = 25.83
     \]

### 2) \( 0.62 \times 0.45 \)
   - Multiply the two numbers:
     \[
     0.62 \times 0.45 = 0.279
     \]

### 3) \( 0.008 \times 15.4 \)
   - Multiply the two numbers:
     \[
     0.008 \times 15.4 = 0.1232
     \]

### 4) \( 5.17 \times 21.2 \)
   - Multiply the two numbers:
     \[
     5.17 \times 21.2 = 109.604
     \]

### 5) \( 6.8 \times 0.0024 \)
   - Multiply the two numbers:
     \[
     6.8 \times 0.0024 = 0.01632
     \]

### 6) \( 3.18 \times 1.526 \)
   - Multiply the two numbers:
     \[
     3.18 \times 1.526 = 4.85468
     \]

### 7) A bottle of water contains 16.9 ounces. How many total ounces are there in a case with 24 bottles?
   - Multiply the number of ounces by the number of bottles:
     \[
     16.9 \times 24 = 405.6 \, \text{ounces}
     \]

### 8) Abraham ran 3.18 miles on Monday. On Tuesday, he ran 1.6 times further than he did on Monday. How many more miles did he run on Tuesday than on Monday?
   - First, find how much Abraham ran on Tuesday:
     \[
     3.18 \times 1.6 = 5.088 \, \text{miles}
     \]
   - Then subtract the miles he ran on Monday from the miles on Tuesday:
     \[
     5.088 - 3.18 = 1.908 \, \text{miles}
     \]
   So, Abraham ran 1.908 more miles on Tuesday than on Monday.

If you'd like more details or have any questions, feel free to ask!

Here are 5 additional questions to deepen your understanding:

1. What is the rule for multiplying two decimal numbers?
2. How would rounding affect your answers for each product?
3. Can you express 405.6 ounces from question 7 in gallons (1 gallon = 128 ounces)?
4. If Abraham ran 3.18 miles each day for a week, how many miles would he run in total?
5. How would the calculation change if Abraham ran 2.5 times further on Tuesday?

**Tip:** When multiplying decimals, the total number of decimal places in the product is the sum of the decimal places in the numbers being multiplied.

The original question is about multiplying decimals and related word problems, such as multiplying ounces and calculating miles.

Solve problems involving multiplication of decimals, including products such as 2.87 × 9 and 0.62 × 0.45. Also covers word problems like calculating total ounces in water bottles and distance run by Abraham. Suitable for Grades 4-6.
