first estimate how many pieces of cheese the mouse would eat in 12 minutes. would it be more or less than 30 pieces of cheese?
pieces of cheese | minutes
30 | 10
? | 12
the mouse would eat less than 30 pieces of cheese in 12 minutes.
the mouse would eat more than 30 pieces of cheese in 12 minutes.

Explanation:

Step1: Analyze time change

12 minutes > 10 minutes

Step2: Relate to cheese consumption

More time means more cheese eaten.

Step3: Calculate exact amount (optional)

First find rate: $\frac{30}{10} = 3$ pieces per minute.
Cheese in 12 minutes: $3 \times 12 = 36$ pieces.
36 > 30, so more than 30.

Answer:

The mouse would eat more than 30 pieces of cheese in 12 minutes.
