Jared and 5 friends wanted to make mac and cheese for lunch. they decided to use 3 boxes and each box needs 1` 2/3 cups of milk. the milk carton has 4 cups of milk left in it. do they have enough milk to make their lunch? Prove answer

I put
Yes because if 1 box needs 1 2/3 cups of milk than that means boxes need 3 2/3 cups of milk and there is 4 cups.

How did you multiply 1 2/3 by 3 and get 3 2/3?

Try again.

To determine if Jared and his 5 friends have enough milk to make their mac and cheese lunch, we need to compare the amount of milk required with the amount of milk available.

First, let's calculate the total milk required for the 3 boxes of mac and cheese. Each box requires 1 2/3 cups of milk. Therefore, to find the total amount of milk needed, we multiply 1 2/3 by 3:

1 2/3 cups * 3 = 5 cups.

So, 3 boxes of mac and cheese require a total of 5 cups of milk.

Now, let's compare this with the amount of milk available. The milk carton has 4 cups of milk. Since the amount of milk needed (5 cups) is greater than the amount of milk available (4 cups), it seems initially that they do not have enough milk to make their lunch.

However, we can simplify this situation by using mixed numbers. The mixed number 1 2/3 can be converted to an improper fraction:

1 2/3 = (1 * 3 + 2) / 3 = 5/3 cups.

Therefore, each box of mac and cheese requires 5/3 cups of milk.

Now, let's calculate the total milk required in terms of thirds. Since we have 3 boxes, each requiring 5/3 cups of milk, the total amount of milk required is:

3 * (5/3) = 15/3 = 5 cups.

Surprisingly, this is the same amount of milk that they have available. The amount of milk required (5 cups) is exactly equal to the amount of milk available (4 cups) in this case.

Therefore, even though it initially seemed like they did not have enough milk to make their lunch, Jared and his friends actually have exactly enough milk to make the mac and cheese.

In conclusion, they do have enough milk to make their lunch, as the amount of milk required (5 cups) matches the amount of milk available (4 cups).
