Answer 1

He could have groups of 6, and have three groups in sixth grade and 4 in 7th grade.

Answer 2

Answer:

groups of 6 students.

Step-by-step explanation:

Mr. Ramirez has 18 sixth grade students and 24 seventh grade students.

He wants to put the students in equal group of only one grade students.

So we calculate the HCF of the numbers.

18 = 2 × 3 × 3

24 = 2 × 2 × 2 × 3

= 2 × 3

HCF = 6

Hence there would be 6 students group for each grade

6th grade = 6 + 6 + 6  = 18 students

7th grade = 6 + 6 + 6 + 6  = 24 students

Total 7 groups of 6 students would be made.
