Problem 1:

Mrs. Smith is planning a class party for 18 students. She will be serving apple juice. If she serves 250 ml per student, how many liters of juice will she need to buy?

#### Solution:
1. Calculate the total amount of juice needed in milliliters:
\[
\text{Total juice} = \text{Number of students} \times \text{Juice per student}
\]
\[
\text{Total juice} = 18 \times 250 \, \text{ml} = 4500 \, \text{ml}
\]

2. Convert milliliters to liters:
\[
1 \, \text{liter} = 1000 \, \text{ml}
\]
\[
\text{Total juice in liters} = \frac{4500 \, \text{ml}}{1000} = 4.5 \, \text{liters}
\]

#### Answer:
\[
\boxed{4.5}
\]

Problem 2:

Mr. Green’s lawn mower holds 600 milliliters of gasoline in the tank. He just filled his 6-liter gas can at the station. How many times will he be able to fill his lawn mower tank from the gas can?

#### Solution:
1. Convert the capacity of the gas can to milliliters:
\[
1 \, \text{liter} = 1000 \, \text{ml}
\]
\[
\text{Gas can capacity} = 6 \, \text{liters} \times 1000 = 6000 \, \text{ml}
\]

2. Calculate how many times the lawn mower tank can be filled:
\[
\text{Number of fills} = \frac{\text{Gas can capacity}}{\text{Lawn mower tank capacity}}
\]
\[
\text{Number of fills} = \frac{6000 \, \text{ml}}{600 \, \text{ml}} = 10
\]

#### Answer:
\[
\boxed{10}
\]

Problem 3:

While Justin is in training, he is to drink 500 milliliters of water 4 times per day. How many liters of water will that be for one week?

#### Solution:
1. Calculate the daily water intake in milliliters:
\[
\text{Daily water intake} = \text{Water per serving} \times \text{Number of servings per day}
\]
\[
\text{Daily water intake} = 500 \, \text{ml} \times 4 = 2000 \, \text{ml}
\]

2. Calculate the weekly water intake in milliliters:
\[
\text{Weekly water intake} = \text{Daily water intake} \times \text{Number of days in a week}
\]
\[
\text{Weekly water intake} = 2000 \, \text{ml} \times 7 = 14000 \, \text{ml}
\]

3. Convert milliliters to liters:
\[
\text{Weekly water intake in liters} = \frac{14000 \, \text{ml}}{1000} = 14 \, \text{liters}
\]

#### Answer:
\[
\boxed{14}
\]

Problem 4:

A punch recipe calls for 3 liters ginger ale, 1.5 liters tropical fruit juice, and 500 milliliters pineapple juice. How much punch will the recipe make?

#### Solution:
1. Convert all quantities to the same unit (liters):
- Ginger ale: \(3 \, \text{liters}\)
- Tropical fruit juice: \(1.5 \, \text{liters}\)
- Pineapple juice: \(500 \, \text{ml} = \frac{500}{1000} = 0.5 \, \text{liters}\)

2. Add the quantities together:
\[
\text{Total punch} = 3 + 1.5 + 0.5 = 5 \, \text{liters}
\]

#### Answer:
\[
\boxed{5}
\]

Problem 5:

Sean has 3 2-liter bottles of soda. If he divides the soda equally between himself and his 11 friends, how much soda will each person have?

#### Solution:
1. Calculate the total amount of soda in liters:
\[
\text{Total soda} = 3 \times 2 = 6 \, \text{liters}
\]

2. Determine the number of people sharing the soda:
\[
\text{Number of people} = 1 \, (\text{Sean}) + 11 \, (\text{friends}) = 12
\]

3. Calculate the amount of soda per person:
\[
\text{Soda per person} = \frac{\text{Total soda}}{\text{Number of people}}
\]
\[
\text{Soda per person} = \frac{6 \, \text{liters}}{12} = 0.5 \, \text{liters}
\]

4. Convert liters to milliliters:
\[
0.5 \, \text{liters} = 0.5 \times 1000 = 500 \, \text{ml}
\]

#### Answer:
\[
\boxed{500}
\]

Problem 6:

Ann is baking 2 cakes, brownies, cookies, and 2 pies for the bake sale. The recipes call for milk in the following amounts: 230 ml, 50 ml, 120 ml, 200 ml, 300 ml, and 100 ml. How much milk does she need in all?

#### Solution:
1. Add up all the milk requirements:
\[
\text{Total milk} = 230 \, \text{ml} + 50 \, \text{ml} + 120 \, \text{ml} + 200 \, \text{ml} + 300 \, \text{ml} + 100 \, \text{ml}
\]
\[
\text{Total milk} = 1000 \, \text{ml}
\]

2. Convert milliliters to liters:
\[
\text{Total milk in liters} = \frac{1000 \, \text{ml}}{1000} = 1 \, \text{liter}
\]

#### Answer:
\[
\boxed{1}
\]
