Question

Anna cooks 12 cups of tomato soup in a large pot. She fills 4 bowls with 10 fluid ounces of soup each from the pot. How many cups of soup are left in the pot?

Answer 1

To find out how many cups of soup are left in the pot, we first need to determine the total number of cups needed. Converting quarts to cups, we find that there are 15 cups of soup left in the pot.

Step-by-step explanation:

First, find the total number of cups she needs. If there are 3 cups in one batch, and she is making 5 batches, then she will need: 3x5=15 cups. Next, set up a proportion.

4 cups/1 quart=15 cups/x quarts

Finally, solve the proportion for x:

x = (15 cups)(1 quart)/(4 cups)

x = 15/4 quarts

x = 3.75 quarts

Since 1 quart is equal to 4 cups, 3.75 quarts is equal to 3.75 x 4 = 15 cups.

Therefore, there are 15 cups of soup left in the pot.

Answer 2

Anna had 12 cups of soup and after serving 4 bowls of 10 fluid ounces each, 7 cups of soup are left in the pot. We calculated this by converting fluid ounces to cups and then subtracting the served amount from the initial quantity.

Step-by-step explanation:

The student asked, "How many cups of soup are left in the pot after Anna fills 4 bowls with 10 fluid ounces of soup each?" To answer this, we first need to recognize that we are dealing with a unit conversion problem, since we're given fluid ounces and need to find out the leftover amount in cups.

Since 8 fluid ounces equals 1 cup, we can start by converting the 10 fluid ounces for each bowl into cups:

10 fl oz × 1 cup/8 fl oz = 1.25 cups per bowl

Next, we multiply the amount per bowl by the number of bowls:

1.25 cups/bowl × 4 bowls = 5 cups total used

Lastly, subtract the total used from the initial amount in the pot:

12 cups - 5 cups = 7 cups of soup are left in the pot.
