a group or 10 people are ordering pizzas. each person wants 3 slices and each pizza has 8 slices how many pizzas should they order
30 slices (3 * 10) are needed
30 / 8 = ? ... the result should be rounded up to the next whole number
... no partial pizzas
To figure out how many pizzas the group should order, we need to calculate the total number of slices needed. Here's how we can do it step-by-step:
1. Determine the number of slices each person wants: Each person wants 3 slices.
2. Find the total number of slices needed by multiplying the number of slices per person by the number of people: 3 slices/person * 10 people = 30 slices.
3. Calculate the number of pizzas needed by dividing the total number of slices by the number of slices per pizza: 30 slices / 8 slices/pizza = 3.75 pizzas.
Since you can't order a fraction of a pizza, the group should order 4 pizzas to have enough slices for everyone.
To find out how many pizzas the group of 10 people should order, we first need to calculate the total number of slices needed.
Since each person wants 3 slices, we multiply the number of people (10) by the number of slices each person wants (3):
10 people * 3 slices/person = 30 slices
Next, we divide the total number of slices needed (30) by the number of slices per pizza (8) to determine the number of pizzas required:
30 slices ÷ 8 slices/pizza = 3.75 pizzas
Since we can't order a fraction of a pizza, we need to round up to the nearest whole number.
Therefore, the group of 10 people should order 4 pizzas to ensure everyone gets enough slices.
