Explanation:

Let's solve some of these problems step by step. We'll start with problem 18:

Problem 18:

Step 1: Recall the conversion factor

We know that 1 meter = 100 centimeters, so to convert centimeters to meters, we divide by 100.

Step 2: Apply the conversion

The length of the porch is 500 centimeters. So we calculate $500 \div 100$.
$500 \div 100 = 5$

Step 1: Recall the conversion factor

1 meter = 100 centimeters, so to convert meters to centimeters, we multiply by 100.

Step 2: Apply the conversion

We have 34 meters. So we calculate $34 \times 100$.
$34 \times 100 = 3400$

Step 1: Recall the conversion factor

1 centiliter (cL) = 10 milliliters (mL), so to convert milliliters to centiliters, we divide by 10.

Step 2: Apply the conversion

We have 499 mL. So we calculate $499 \div 10$.
$499 \div 10 = 49.9$

Answer:

The front porch is 5 meters long.
