There are 154 seats in the school auditorium. There are 7 seats in each row. There are 70 people seated, filling up full rows of seats.
How many rows are empty?
To find out how many rows are empty in the school auditorium, we first need to determine the total number of rows filled with people.
We can calculate this by dividing the total number of people seated by the number of seats in each row. In this case, there are 70 people seated and 7 seats in each row, so we can divide 70 by 7:
70 ÷ 7 = 10
Therefore, there are 10 rows completely filled with people.
To find out how many rows are empty, we subtract the number of filled rows from the total number of rows in the auditorium. In this case, there are 154 seats in the auditorium and 7 seats in each row, so we can divide 154 by 7:
154 ÷ 7 = 22
Since there are 10 filled rows, we subtract this from the total number of rows to find the number of empty rows:
22 - 10 = 12
Therefore, there are 12 empty rows in the school auditorium.
there are (154 / 7) rows
(70 / 7) are filled
