Let us count the number of wheels in cars. Number of wheels in 10 cars with 4 wheels in each is $10 \times 4$ wheels = ____ wheels. Number of wheels in 30 cars with 4 wheels in each is $30 \times 4$ wheels = ____ + ____ + ____ = ____ wheels.

Correct Answer

Number of wheels in 10 cars = 40 wheels. Number of wheels in 30 cars = 40 + 40 + 40 = 120 wheels. $10 \times 4$ = 40. $30 \times 4$ = 120.

Explanation

The chapter extends the concept to multiplication with 30. For 10 cars with 4 wheels each: $10 \times 4$ = 40 wheels. For 30 cars: $30 \times 4$ = (10 + 10 + 10) × 4 = 40 + 40 + 40 = 120 wheels. This shows the relationship between $10 \times 4$ and $30 \times 4$ .

Solution Steps

Step 1: 10 cars × 4 wheels = 40 wheels
Step 2: 30 cars = 10 + 10 + 10 cars
Step 3: $30 \times 4$ = 40 + 40 + 40 = 120 wheels
