Here are the solutions to the problems.

2.

Convert the total amount of food from kilograms to grams.
$1.5 \text{ kg} = 1.5 \times 1000 \text{ g} = 1500 \text{ g}$
Divide the total amount of food by the daily consumption to find the number of days.
$\text{Number of days} = \frac{\text{Total food}}{\text{Food per day}}$ $\text{Number of days} = \frac{1500 \text{ g}}{30 \text{ g/day}}$ $\text{Number of days} = 50 \text{ days}$
The packet of food will last for $\boxed{\text{50 days}}$ .

3.
Convert the total volume of lemonade from litres to millilitres.
$1 \text{ litre} = 1000 \text{ millilitres}$
Calculate the total amount of lemonade used for 5 glasses.
$\text{Lemonade used} = \text{Number of glasses} \times \text{Volume per glass}$ $\text{Lemonade used} = 5 \times 150 \text{ mL}$ $\text{Lemonade used} = 750 \text{ mL}$
Subtract the used lemonade from the total lemonade to find the amount left.
$\text{Lemonade left} = \text{Total lemonade} - \text{Lemonade used}$ $\text{Lemonade left} = 1000 \text{ mL} - 750 \text{ mL}$ $\text{Lemonade left} = 250 \text{ mL}$
There is $\boxed{\text{250 millilitres}}$ of lemonade left in the bottle.
