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?

#### Step 1: Convert liters to milliliters
We know:
- 1 liter = 1000 milliliters

So,
- 18 liters = 18 × 1000 = 18,000 milliliters

#### Step 2: Divide total volume by bottle capacity
Each bottle holds 600 mL.

Number of bottles =
$$
\frac{18,000}{600} = 30
$$

✔ Answer: 30 bottles

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?

#### Step 1: Convert pounds to ounces
We know:
- 1 pound = 16 ounces

So,
- 3 pounds = 3 × 16 = 48 ounces

#### Step 2: Divide total ounces by serving size
Each serving is 8 ounces.

Number of servings =
$$
\frac{48}{8} = 6
$$

✔ Answer: 6 servings

Problem 3:

A candy maker uses 4 pints of cream to make caramels. The cream is added slowly, ½ cup at a time. How many times will the cream be added to use all 4 pints?

#### Step 1: Convert pints to cups
We know:
- 1 pint = 2 cups

So,
- 4 pints = 4 × 2 = 8 cups

#### Step 2: Divide total cups by amount added each time
Each addition is ½ cup.

Number of additions =
$$
\frac{8}{0.5} = 16
$$

✔ Answer: 16 times

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?

#### Step 1: Convert units to be the same
Convert 400 mm to centimeters:
- 1 cm = 10 mm → So, 400 mm = 400 ÷ 10 = 40 cm

Salamander length = 8 cm

#### Step 2: Divide tank length by salamander length
$$
\frac{40}{8} = 5
$$

✔ Answer: 5 times longer
