An event planner expects 432 teachers to attend a conference. if the planner places 24 chairs in each row, estimate the number of rows needed to provide seating for all of the teachers.

The number of rows needed to provide seating for all  teachers is 18.

Step-by-step explanation:

Here, the total number of guests expected to attend = 432 teachers

Now,  given : The number of chairs placed in each row = 24

Let us assume , the total number of rows of chairs  = m

Now, The total chairs in the conference room

= The number of rows x The chairs in each row

=  24 x (m)  = 24 m

Also, the TOTAL CHAIRS  = TOTAL GUEST EXPECTED

⇒ 24 m = 432

or,  m = 432 / 24 = 18

or, m = 18

Hence, the number of rows needed to provide seating for all of the teachers is 18.

17.08

correct me if i am wrong.

you just switch the numbers basically so it would be 3/17
