Here are the solutions to the four liquid measurement problems, worked out step by step.
Problem 1: The Lemonade Company
*
Step 1: Identify the total amount of lemonade available. The problem states there are
24 liters.
*
Step 2: Identify the size of each bottle. Each bottle holds
2 liters.
*
Step 3: To find out how many bottles can be filled, divide the total liters by the size of one bottle.
* Calculation: $24 \div 2 = 12$
*
Result: They can fill 12 bottles.
Problem 2: Estimate the Capacity of a Cup
*
Step 1: Look at the object, which is a standard tea or coffee cup.
*
Step 2: Think about real-world measurements. A standard liter is roughly the size of a large water bottle or a quart of milk.
*
Step 3: Compare the cup to a liter. A single cup usually holds about 200 to 250 milliliters. Since 1,000 milliliters make 1 liter, a cup is much smaller than a liter.
*
Result: The capacity is less than a liter.
Problem 3: Blender Capacity Estimate
*
Step 1: Look at the two options:
2 milliliters and
2 liters.
*
Step 2: Visualize the amounts.
* 2 milliliters is a tiny amount, like just a few drops from an eyedropper or half a teaspoon. This is too small for a blender.
* 2 liters is a larger amount, similar to a big soda bottle. Blenders are designed to hold enough liquid for multiple servings of smoothies.
*
Step 3: Choose the estimate that makes sense for the size of the appliance.
*
Result: 2 liters is the best estimate.
Problem 4: Bruno's Vitamins
*
Step 1: Identify the daily amount. Bruno takes
9 ml every day.
*
Step 2: Identify the time period. The question asks for the total amount in a
week.
*
Step 3: Remember how many days are in a week. There are
7 days in a week.
*
Step 4: Multiply the daily amount by the number of days.
* Calculation: $9 \text{ ml} \times 7 \text{ days} = 63 \text{ ml}$
*
Result: He would take 63 milliliters in a week.
