Options

A. 90 L 450 mL
B. 90 L 250 mL
C. 90 L 455 mL
D. 90 L 500 mL

Answer

To solve the problem step by step, we need to find out the quantity of milk in 45 bottles based on the information given about 25 bottles.

### Step 1: Convert the total quantity of milk into a single unit
We are given 50 liters and 250 milliliters of milk. First, we need to convert everything into milliliters for easier calculations.

- 1 liter = 1000 milliliters
- Therefore, 50 liters = 50 × 1000 = 50000 milliliters
- Now, add the 250 milliliters:
\[ 50000 \text{ mL} + 250 \text{ mL} = 50250 \text{ mL} \]

### Step 2: Calculate the quantity of milk in one bottle
Now that we have the total quantity of milk in milliliters, we can find out how much milk is in one bottle.

- We have 25 bottles, so to find the quantity of milk in one bottle, we divide the total quantity by the number of bottles:
\[ \text{Quantity in one bottle} = \frac{50250 \text{ mL}}{25} = 2010 \text{ mL} \]

### Step 3: Calculate the quantity of milk in 45 bottles
Now we need to find out how much milk is in 45 bottles.

- We multiply the quantity of milk in one bottle by 45:
\[ \text{Quantity in 45 bottles} = 2010 \text{ mL} \times 45 = 90450 \text{ mL} \]

### Step 4: Convert the result back to liters and milliliters
Finally, we convert 90450 milliliters back into liters and milliliters.

- To convert to liters, we divide by 1000:
\[ 90450 \text{ mL} = 90 \text{ L} + 450 \text{ mL} \]

### Final Answer
The quantity of milk in 45 bottles is **90 liters and 450 milliliters**.
