Final answer:
To make two groups out of 22 students such that the first group has 8 students less than the second group, you can divide the total number of students in half, and then subtract 8 from the second group to ensure it has 8 students more than the first group.
Step-by-step explanation:
To make two groups out of 22 students such that the first group has 8 students less than the second group, we can start by dividing the total number of students in half. Half of 22 is 11. So, we can start by placing 11 students in the first group. Now, we need to subtract 8 from the second group to ensure it has 8 students more than the first group. 11 - 8 = 3. Therefore, the first group will have 11 students and the second group will have 3 students.
