Answer 1

Если 12
1)12×12=144
если 16
2)16*9=144

Answer 2

Calculation of the Number of Sixth Graders Going on the Excursion

To determine the number of sixth graders going on the excursion, we need to find the number of students that can be accommodated in either a 12-person or a 16-person minibus. The number of students should be greater than 120 but less than 150.

Let's calculate the number of students for each scenario:

1. Minibuses with 12 seats: - The number of students that can be accommodated in each minibus is 12. - To find the number of minibuses needed, we divide the total number of students by 12. - The number of students should be greater than 120 but less than 150, so the possible range is 121 to 149. - Let's calculate the number of minibuses needed for each possible number of students in this range:

- For 121 students: 121 / 12 = 10 minibuses - For 122 students: 122 / 12 = 10 minibuses - For 123 students: 123 / 12 = 10 minibuses - ... - For 149 students: 149 / 12 = 12 minibuses

2. Minibuses with 16 seats: - The number of students that can be accommodated in each minibus is 16. - To find the number of minibuses needed, we divide the total number of students by 16. - The number of students should be greater than 120 but less than 150, so the possible range is 121 to 149. - Let's calculate the number of minibuses needed for each possible number of students in this range:

- For 121 students: 121 / 16 = 7.5625 minibuses (round up to 8 minibuses) - For 122 students: 122 / 16 = 7.625 minibuses (round up to 8 minibuses) - For 123 students: 123 / 16 = 7.6875 minibuses (round up to 8 minibuses) - ... - For 149 students: 149 / 16 = 9.3125 minibuses (round up to 10 minibuses)

Based on the calculations, we can see that the number of students going on the excursion will be the same regardless of whether minibuses with 12 seats or minibuses with 16 seats are used. The number of students will be between 121 and 149.

Therefore, the number of sixth graders going on the excursion cannot be determined with the given information.
