Answer:

(a)0.3 kg (b)1 kg (c)0.5l

Step-by-step explanation:

Part 1.1.1

$\begin{gathered} 1000g=1\operatorname{kg} \\ 1g=(1)/(1000)kg \\ \implies300\text{grams}=300*(1)/(1000)kg \\ =(300)/(1000)kg \\ =0.3\operatorname{kg} \end{gathered}$

Part 1.1.2

The recipe calls for 400g of tomatoes for 2 people.

Since Jane's family consists of 5 people (including herself):

$\begin{gathered} (2)/(400)=(5)/(x) \\ 2x=5*400 \\ x=(5*400)/(2) \\ x=1000g \\ x=1\operatorname{kg} \end{gathered}$

Jane will need 1 kg of tomatoes to make this recipe for her family.

Part 1.1.3

Next, we convert 500ml to liters.

$\begin{gathered} 1ml=0.001\; l \\ 500\; ml=0.001*500\; l \\ =0.5\; \text{liters} \end{gathered}$

500ml is 0.5 liters.

Part 1.1.4
