The Crane family is setting up for their fundraiser for their children's school. There will be 45 adults and 109 children coming in the evening. Each table holds 9 people. How many tables will they need for all guests?

it is 18

What is (45+109)/9 ?

assuming there are no restrictions as to how many children or adults
for a table. Do you realize that if the above division has a remainder,
they will need an extra table.

mmmm... wonder if they can squeeze that 1 extra person in one
of the tables.

The Diaz family is setting up for their annual End-Of-Summer bash. There will be 66 adults and 23 children coming in the evening. Each table holds 7 people. How many tables will they need for all guests?

To determine the number of tables needed for all guests, we need to calculate the total number of guests and divide it by the capacity of each table.

First, let's calculate the total number of guests:
Number of adults = 45
Number of children = 109
Total number of guests = Number of adults + Number of children

Total number of guests = 45 + 109 = 154

Now, let's calculate the number of tables needed:
Capacity of each table = 9
Number of tables needed = Total number of guests ÷ Capacity of each table

Number of tables needed = 154 ÷ 9 ≈ 17.11 (round up to the nearest whole number)

Therefore, the Crane family will need approximately 18 tables for all their guests.
