Let's solve each problem step by step.
---
Problem 1:
Coach Bill brought 18 liters of water to the track meet. He poured the water into smaller bottles, each of which held 600 milliliters. How many water bottles did he need to hold all of the water?
####
Solution:
1.
Convert liters to milliliters:
- 1 liter = 1000 milliliters
- Therefore, 18 liters = \( 18 \times 1000 = 18000 \) milliliters
2.
Determine how many bottles are needed:
- Each bottle holds 600 milliliters.
- Number of bottles required = Total milliliters ÷ Milliliters per bottle
- Number of bottles = \( \frac{18000}{600} = 30 \)
####
Answer:
\[ \boxed{30} \]

Problem 2:
Arian's dog eats 8 ounces of dog food each day. Arian bought a 3-pound bag of dog food. How many 8-ounce servings are in a 3-pound bag of dog food?
####
Solution:
1.
Convert pounds to ounces:
- 1 pound = 16 ounces
- Therefore, 3 pounds = \( 3 \times 16 = 48 \) ounces
2.
Determine the number of 8-ounce servings:
- Number of servings = Total ounces ÷ Ounces per serving
- Number of servings = \( \frac{48}{8} = 6 \)
####
Answer:
\[ \boxed{6} \]

Problem 3:
A candy maker uses 4 pints of cream to make caramels. The cream is added slowly, 1/2 cup at a time. How many times will the cream be added to use all 4 pints?
####
Solution:
1.
Convert pints to cups:
- 1 pint = 2 cups
- Therefore, 4 pints = \( 4 \times 2 = 8 \) cups
2.
Determine how many times the cream is added:
- Each addition is 1/2 cup.
- Number of additions = Total cups ÷ Cups per addition
- Number of additions = \( \frac{8}{\frac{1}{2}} = 8 \times 2 = 16 \)
####
Answer:
\[ \boxed{16} \]

Problem 4:
Molly's pet salamander has a tank that is 400 mm in length. Her salamander has a length of 8 cm. How many times longer is the tank than the salamander?
####
Solution:
1.
Convert the tank's length to centimeters:
- 1 cm = 10 mm
- Therefore, 400 mm = \( \frac{400}{10} = 40 \) cm
2.
Determine how many times longer the tank is compared to the salamander:
- Tank length = 40 cm
- Salamander length = 8 cm
- Ratio = \( \frac{\text{Tank length}}{\text{Salamander length}} = \frac{40}{8} = 5 \)
####
Answer:
\[ \boxed{5} \]
---
Final Answers:
1. \( \boxed{30} \)
2. \( \boxed{6} \)
3. \( \boxed{16} \)
4. \( \boxed{5} \)
