A teapot has 2.5L of tea. It is poured in cups with a capacity of 250 mL each. How many cups can be filled?
The Correct Answer and Explanation is:
Correct Answer:
10 cups can be filled.
Explanation s):
To find out how many cups can be filled with tea from a teapot, we need to compare the total volume of tea with the capacity of each cup. However, both quantities must be in the same unit before performing any calculation.
The problem gives:
- Total tea in the teapot = 2.5 liters
- Capacity of one cup = 250 milliliters
We need to convert liters to milliliters because the cup size is given in milliliters.
The conversion factor is:
1 liter = 1,000 milliliters
So,
2.5 liters = 2.5 × 1,000 = 2,500 milliliters
Now that both measurements are in milliliters, we can divide the total volume by the volume of one cup:
2,500 milliliters ÷ 250 milliliters = 10
Therefore, 10 full cups can be filled with tea from the teapot.
This kind of problem involves basic unit conversion and division. It is important to always convert to the same units before performing arithmetic operations. In this case, converting liters to milliliters makes it easy to divide by the cup size. Alternatively, we could have also converted the cup size to liters and then performed the division, but using milliliters is more straightforward in this context.
This example is a practical way to understand ratios and proportions in everyday life. Whether you are working with recipes, liquid measurements, or even fuel calculations, converting units and dividing quantities are essential skills. Understanding how many containers a given amount can fill is useful not only in math problems but also in cooking, science experiments, and inventory management.
