Question

a car has four wheels. how many wheels are there for 18 cars?

cars	1	2	20	$square$

Explanation:

Step1: Identify the relationship

Each car has 4 wheels, so wheels = cars × 4.

Step2: Calculate for 18 cars

For 18 cars, wheels = \( 18 \times 4 \).
\( 18 \times 4 = 72 \)

Step3: Fill the table

In the cars row, the last cell is 18. In the wheels row, the last cell is 72.

Answer:

In the cars column (the last empty cell), we put 18, and in the wheels column (the last empty cell), we put 72. So the filled table cells are 18 (cars) and 72 (wheels).
