Which jug holds more: A or B?

• i) $20000 \text{ ml} = 20000 \times \frac{1}{1000} \ell = 20 \ell$
• ii) $20000 \ell$
• iii) $2000 \text{ kl} = 2000 \times 1000 \ell = 2000000 \ell$

The correct option is iii).

2. e) How can you check each of your answers?
You can check by researching the standard capacities of these items (teaspoon, bucket, bath, Olympic pool) and converting units to ensure consistency.

3. Jug A

a) Does jug A hold more or less than 1 litre?

Assuming the units are millilitres (ml), as is common for measuring jugs.

$1 \text{ litre} = 1000 \text{ ml}$.

Jug A holds less than 1 litre.

b) How much can jug A hold, if you fill it to the top mark?
The top mark on Jug A is 500.

c) What does each mark in between the numbers show?

The difference is $200 - 100 = 100 \text{ ml}$.

There are 5 intervals.

$\frac{100 \text{ ml}}{5} = 20 \text{ ml}$.
Each mark shows 20 ml.

d) About how much milk is in the jug?

The milk level is at the second mark above $200 \text{ ml}$.

$2 \times 20 \text{ ml} = 40 \text{ ml}$.

$200 \text{ ml} + 40 \text{ ml} = 240 \text{ ml}$.
There is about 240 ml of milk in Jug A.

3. Jug B

a) Does jug B hold more or less than 1 litre?

Assuming the units are millilitres (ml).

$1 \text{ litre} = 1000 \text{ ml}$.

Jug B holds exactly 1 litre.

b) How much can this jug hold, if you fill it to the top mark?
The top mark on Jug B is 1000.

c) What does each mark in between the numbers show?

The difference is $400 - 200 = 200 \text{ ml}$.

There are 5 intervals.

$\frac{200 \text{ ml}}{5} = 40 \text{ ml}$.
Each mark shows 40 ml.

d) About how much milk is in the jug?

The milk level is at the first mark above $200 \text{ ml}$.

$1 \times 40 \text{ ml} = 40 \text{ ml}$.

$200 \text{ ml} + 40 \text{ ml} = 240 \text{ ml}$.
There is about 240 ml of milk in Jug B.

Which jug holds more: A or B?

$1000 \text{ ml} > 500 \text{ ml}$.
Jug B holds more.
