Explanation:

Sub - Question 1

Step1: Identify equal groups

Each wagon is a group with 4 wheels, and there are 3 groups (wagons). To find the total number of wheels, we use multiplication, which is repeated addition of equal groups. The formula for the total number of wheels \( W \) is \( W=\text{number of wheels per wagon}\times\text{number of wagons} \). Here, number of wheels per wagon \( = 4 \) and number of wagons \( = 3 \).

Step2: Calculate the total

Using the formula \( W = 4\times3\). \( 4\times3=12 \).

Step1: Identify equal groups

Each scooter is a group with 2 wheels, and there are 5 groups (scooters). The formula for the total number of wheels \( W \) is \( W=\text{number of wheels per scooter}\times\text{number of scooters} \). Here, number of wheels per scooter \( = 2 \) and number of scooters \( = 5 \).

Step2: Calculate the total

Using the formula \( W=2\times5 \). \( 2\times5 = 10 \).

Answer:

The 3 wagons have 12 wheels.
