a. What fraction is 300 mL of `1 (1)/(2)` litres?

Answer

To find the fraction that represents 300 mL of 1 1/2 liters, we can follow these steps:

### Step 1: Convert 1 1/2 liters to milliliters
1. **Convert liters to milliliters**:
- 1 liter = 1000 mL
- Therefore, 1 1/2 liters = 1 liter + 1/2 liter
- 1 liter = 1000 mL
- 1/2 liter = 500 mL
- So, 1 1/2 liters = 1000 mL + 500 mL = 1500 mL

### Step 2: Set up the fraction
2. **Set up the fraction**:
- We need to find what fraction 300 mL is of 1500 mL.
- The fraction can be expressed as:
\[ \text{Fraction} = \frac{300 \text{ mL}}{1500 \text{ mL}} \]

### Step 3: Simplify the fraction
3. **Simplify the fraction**:
- We can simplify \(\frac{300}{1500}\) by dividing both the numerator and the denominator by 300.
\[ \frac{300 \div 300}{1500 \div 300} = \frac{1}{5} \]

### Final Answer
The fraction that represents 300 mL of 1 1/2 liters is \(\frac{1}{5}\).
