The Odgen School marching band has 91 musicians. If there are 7 student musicians in each row, how many rows are there?

91 / 7 = ?

Use prime factorization.

To find out how many rows there are, we need to divide the total number of musicians by the number of musicians in each row. In this case, there are 91 musicians in the Odgen School marching band and 7 musicians in each row.

To calculate the number of rows, divide the total number of musicians by the number of musicians in each row:

91 musicians ÷ 7 musicians/row = 13 rows

Therefore, the Odgen School marching band has 13 rows.
