In an auditorium, there are 9 rows of seats with 18 seats in each row .There also 6 rows of seats with 24 seats in each row. How many seats are ther ein the auditorium? Estimate first. Then checkfor reasonableness.
You multiply 9 by 18 to see how many chairs are there, you then get 162. Then to see the next 6 rows you multiply 6 by 24 which gives you 144. You add both to get 306. Hope it helped :)
