Ethan ordered 4 sub sandwiches for a party. Each 1/2 sandwich is one serving. Does he have enough to serve 7 friends? How much is leftover or how much more is needed? Explain.
4*2=8 servings
(This means he has 8 halves, therefore he does have enough to serve his friends)
He will have one leftover because 8-7=1
Ethan ordered 4 sub sandwiches for a party.Each 1/2 sandwich is one serving.Does he have enough to serve 7 friends? How much is leftover or how much more is needed?
To determine whether Ethan has enough sub sandwiches to serve 7 friends, we need to compare the number of servings he has with the number of servings needed.
First, let's find out how many servings Ethan has. He ordered 4 sub sandwiches, and each 1/2 sandwich is one serving. So, 4 sandwiches * 1/2 serving per sandwich = 4/2 servings = 2 servings.
Therefore, Ethan has 2 servings of sub sandwiches.
Now, let's calculate the number of servings needed for 7 friends. Since each 1/2 sandwich is one serving, 7 friends * 1 serving per friend = 7 servings.
Therefore, Ethan needs 7 servings of sub sandwiches.
Since we have determined that Ethan has 2 servings but needs 7 servings, we can conclude that he does NOT have enough to serve 7 friends.
To calculate how much more is needed, we subtract the number of servings Ethan has (2 servings) from the number of servings needed (7 servings).
7 servings - 2 servings = 5 servings.
Therefore, Ethan needs 5 more servings to serve all 7 friends.
In terms of leftovers, if Ethan initially had more than enough servings (i.e., if he had 7 or more servings), then the leftovers would be the difference between the initial number of servings and the number needed. However, in this case, Ethan does not have enough servings, so there would be no leftovers.
