Final answer:
To find out how many cookies are in each row of an Oreo package with 51 cookies and 3 rows, divide the total number of cookies by the number of rows, resulting in 17 cookies per row.
Step-by-step explanation:
The question involves dividing the total number of cookies in an Oreo package by the number of rows to find out how many cookies there are in each row. Given that there are 51 cookies and 3 rows of cookies per package, we can perform a simple division to find the answer.
To calculate the number of cookies per row, we divide the total number of cookies, which is 51, by the number of rows, which is 3. The calculation is as follows:
51 cookies ÷ 3 rows = 17 cookies per row.
Therefore, each row contains 17 cookies.
