Answer 2

Problem 1: Number of performers on the square

To find the total number of people who performed on the square, we need to calculate the sum of the dancers and the choir members.

Given: - 7 dance groups with 23 people each - 4 choir groups with 43 people each

To find the total number of dancers, we multiply the number of dance groups by the number of people in each group: 7 dance groups * 23 people/group = 161 dancers.

To find the total number of choir members, we multiply the number of choir groups by the number of people in each group: 4 choir groups * 43 people/group = 172 choir members.

Finally, to find the total number of people who performed on the square, we add the number of dancers and the number of choir members: 161 dancers + 172 choir members = 333 people.

Therefore, there were 333 people who performed on the square.

Problem 2: Number of children at the competition

To find the total number of children who attended the competition, we need to calculate the sum of the number of boys and the number of girls.

Given: - 48 boys attended the competition - The number of boys is 4 times greater than the number of girls

To find the number of girls, we divide the number of boys by 4: 48 boys / 4 = 12 girls.

To find the total number of children, we add the number of boys and the number of girls: 48 boys + 12 girls = 60 children.

Therefore, a total of 60 children attended the competition.
