Question

Mrs. Smitherman is coordinating the third- and fourth-grade program. She wishes to arrange the children to the fewest number of rows that contain the same number of children. She also does not wish to mix be classes within a row. If there are 60 third graders and 48 fourth graders, how many children should be aced in each row? How many rows will be needed?​

Answer 1

Number of students in each row = 12

Total number of rows = 9

Explanation:

We have to assume that each row can seat the same number of students

Find the GCF(greatest common factor) of 60 and 48 to find the number of students in each row

60 = 12 x 5

48 = 12 x 4

The GCF = 12

So there are 12 students per row

If there are 60 third-grade students they will occupy 60/12 = 5 rows
48 fourth grade students will occupy 48/12 = 4 rows

Therefore the total number of rows = 5 + 4 = 9 rows
