Answer 3

Calculation of Full and Incomplete Rows

To determine the number of full and incomplete rows in a class of 30 students, where they are arranged in rows of 8 students each, we can use simple division and modulo operations.

To calculate the number of full rows, we divide the total number of students by the number of students in each row:

Number of full rows = Total number of students / Number of students in each row

In this case, the total number of students is 30 and the number of students in each row is 8:

Number of full rows = 30 / 8 = 3.75

Since we cannot have a fraction of a row, we take the whole number part of the result, which is 3. Therefore, there are 3 full rows.

To calculate the number of students in the incomplete row, we use the modulo operation:

Number of students in the incomplete row = Total number of students % Number of students in each row

Number of students in the incomplete row = 30 % 8 = 6

Therefore, there are 3 full rows and 6 students in the incomplete row.

Answer:

In the given class of 30 students, they can be arranged in 3 full rows of 8 students each, with an additional incomplete row of 6 students.
