Final answer:
There are 78 students in the engineering club, and with 6 students per group, there will be 13 groups in total.
Step-by-step explanation:
To calculate the number of groups of students in the engineering club, we can divide the total number of students by the number of students in each group. There are 78 students in the engineering club and the sponsor wants to put 6 students in each group.
To find the number of groups, we perform the calculation:
Number of groups = Total number of students ÷ Number of students per group
Number of groups = 78 ÷ 6
Number of groups = 13
So, there will be 13 groups of 6 students each in the engineering club.
