A group of nine people are ordering pizza each person wants three slices and pizza has eight slices how many pizzas should they order
To determine how many pizzas the group should order, we need to calculate the total number of slices needed and then divide it by the number of slices in each pizza.
First, let's calculate the total number of slices needed. Since each person wants three slices and there are nine people in the group, we can multiply 3 by 9:
3 slices/person * 9 people = 27 slices
Now, we divide this number by the number of slices in each pizza (which is 8) to find out how many pizzas are required:
27 slices ÷ 8 slices/pizza = 3.375 pizzas
It is not possible to order a fraction of a pizza, so we need to round up to the nearest whole number. In this case, we would round up to 4 pizzas to ensure everyone gets enough slices.
Therefore, the group should order at least 4 pizzas to ensure that each person gets three slices.
