What per cent of 1 litre is 200 ml

Answer

To find out what percent of 1 liter is 200 ml, we can follow these steps:

### Step 1: Convert 200 ml to liters
To convert milliliters to liters, we use the conversion factor that 1 liter = 1000 milliliters.

\[ 200 \, \text{ml} = \frac{200}{1000} \, \text{liters} = 0.2 \, \text{liters} \]

### Step 2: Set up the percentage equation
We want to find out what percentage 0.2 liters is of 1 liter. The formula for percentage is:

\[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 \]

In this case, the part is 0.2 liters and the whole is 1 liter.

### Step 3: Substitute the values into the formula
Substituting the values into the percentage formula gives us:

\[ \text{Percentage} = \left( \frac{0.2}{1} \right) \times 100 \]

### Step 4: Calculate the percentage
Now, we calculate the percentage:

\[ \text{Percentage} = 0.2 \times 100 = 20 \]

Thus, 200 ml is 20% of 1 liter.

### Final Answer:
200 ml is 20% of 1 liter.
