One bottle contains 2L Coca Cola drink, how many glasses 100 ml can be filled from it?
The correct answer and explanation is:
Correct Answer:
20 glasses of 100 ml can be filled from one 2-liter bottle of Coca Cola.
Explanation (300 words):
To determine how many 100 ml glasses can be filled from a 2-liter bottle of Coca Cola, we need to understand the relationship between liters (L) and milliliters (ml).
Step 1: Conversion
1 liter is equal to 1000 milliliters (ml).
So, 2 liters = 2 × 1000 = 2000 ml
Step 2: Division
Now, each glass holds 100 ml of Coca Cola.
To find out how many such glasses can be filled from 2000 ml, we divide the total volume by the volume of one glass: 2000 ml100 ml=20 glasses\frac{2000 \, \text{ml}}{100 \, \text{ml}} = 20 \, \text{glasses}
Step 3: Understanding the Units
This calculation is a simple example of unit conversion and division:
- We first convert everything into the same unit (milliliters in this case).
- Then we divide the total amount by the size of each portion to see how many full portions can be made.
Step 4: Real-World Context
This type of problem is practical in everyday life. Suppose you’re hosting a party and want to know how many guests can be served a 100 ml glass of Coke from one 2-liter bottle. The answer is 20 guests. If you need to serve more people, you’ll need more bottles. For example, to serve 40 people 100 ml each, you would need: 40 glasses×100 ml1000 ml/L=4 liters=2 bottles\frac{40 \, \text{glasses} \times 100 \, \text{ml}}{1000 \, \text{ml/L}} = 4 \, \text{liters} = 2 \, \text{bottles}
Conclusion
From one 2-liter bottle, exactly 20 glasses of 100 ml each can be filled. This simple math shows the importance of basic unit conversion and division in everyday planning and estimation tasks.
