Charlie decides he is going to have some friends over for pizza. He estimates that each friend will eat 3 pieces of pizza and knows that East Slide's large pizzas each have 8 slices. How many large pizzas does he need to order if he invites 9 friends? question a- how many large pizza does he need to order if he invited 9 friends. question b- what is the exact amount of slices that will be eaten compared to the whole
To answer your questions:
a) To determine the number of large pizzas Charlie needs to order if he invites 9 friends, you need to calculate the total number of slices required. Since each friend will eat 3 pieces of pizza, the total number of slices needed is 9 friends * 3 slices = 27 slices.
Since each large pizza has 8 slices, divide the total number of slices needed by the number of slices per pizza: 27 slices / 8 slices per pizza = 3.375.
Since we cannot order fractional pizzas, Charlie would need to round up to the nearest whole number. Therefore, Charlie needs to order 4 large pizzas.
b) To determine the exact amount of slices that will be eaten compared to the whole, multiply the number of friends by the number of slices each friend will eat: 9 friends * 3 slices = 27 slices.
In this case, there would be 27 slices eaten compared to the whole.
To answer question a: To determine the number of large pizzas Charlie needs to order if he invites 9 friends, we first need to calculate the total number of pizza slices required.
Charlie estimates that each friend will eat 3 pieces of pizza, so we multiply the number of friends (9) by the number of slices each friend will eat (3). This gives us 9 friends * 3 slices per friend = 27 slices in total.
Now, since each large pizza has 8 slices, we divide the total number of slices required (27) by the number of slices per pizza (8) to find the number of pizzas he needs to order. Using integer division, 27 slices ÷ 8 slices per pizza = 3 pizzas.
Therefore, Charlie needs to order at least 3 large pizzas if he invites 9 friends.
To answer question b: The exact amount of slices that will be eaten compared to the whole can be calculated by multiplying the number of friends (9) by the number of slices each friend will eat (3), which gives us a total of 27 slices.
Since each large pizza has 8 slices, we can divide the total number of slices (27) by the number of slices per pizza (8) to determine how many whole pizzas will be consumed. Using integer division, 27 slices ÷ 8 slices per pizza = 3 whole pizzas.
Therefore, out of the 3 pizzas that Charlie needs to order, he will consume 24 slices (3 pizzas * 8 slices per pizza) out of the total 27 slices required, leaving 3 slices uneaten.
