**3.1.1 Conversion of Pork Roast Mass to Pounds**  
We are given:
- Mass in kilograms: $$ 2.3\,\mathrm{kg} $$  
- Conversion factor: $$ 1\,\mathrm{lb} = 0.45359\,\mathrm{kg} $$

To convert to pounds, we use:
$$
\text{Mass in lb} = \frac{2.3}{0.45359}
$$
Calculating:
$$
\frac{2.3}{0.45359} \approx 5.07\,\mathrm{lb}
$$

**3.1.2 Gun‐smoke Spice in Millilitres**  
We are given:
- $$ 3 $$ tablespoons of spice  
- $$ 1 $$ tablespoon $$ = 15\,\mathrm{ml} $$

Thus, the total in millilitres is:
$$
3 \times 15 = 45\,\mathrm{ml}
$$

**3.1.3 Ratio of Spice to Marinade**  
We have:
- Spice: $$ 45\,\mathrm{ml} $$  
- Marinade: $$ 175\,\mathrm{ml} $$

The ratio is:
$$
45 : 175
$$
Divide both terms by $$ 5 $$ to simplify:
$$
\frac{45}{5} : \frac{175}{5} = 9 : 35
$$

**3.1.4 Oven Off Time Calculation**  
Londi switches on her oven at $$ 14:32 $$ (2:32 PM) and the oven runs for $$ 2 $$ hours $$ 40 $$ minutes. We add the time:
  
- Adding $$ 2 $$ hours to $$ 14:32 $$ gives $$ 16:32 $$.  
- Adding $$ 40 $$ minutes to $$ 16:32 $$ results in:
  $$
  16:32 + 0:40 = 17:12
  $$
  
In analogue (12‑hour) format, this is $$ 5:12\,\mathrm{pm} $$.

**3.1.5 Rounding to the Nearest Tenth**  
Assuming the instruction refers to rounding the converted weight in pounds, we have:
$$
5.07\,\mathrm{lb} \approx 5.1\,\mathrm{lb}\quad \text{(to the nearest tenth)}
$$

**3.2.1 Area of the Kitchen**  
The kitchen is a square with each side of length:
$$
2.8\,\mathrm{m}
$$
The area $$ A $$ is given by:
$$
A = \text{side} \times \text{side} = 2.8 \times 2.8 = 7.84\,\mathrm{m}^2
$$

**3.1.1** 2.3 kg of pork roast is approximately 5.07 pounds. **3.1.2** Londi needs 45 ml of Gun-smoke spice. **3.1.3** The ratio of spice to marinade is 9:35. **3.1.4** Londi will switch off the oven at 5:12 PM. **3.1.5** The weight of the pork roast is approximately 5.1 pounds. **3.2.1** The area of the kitchen is 7.84 square meters.
