Answer:
There are 8 oz of soup per can : True
In 8 cans, there are 21 oz of soup : False
There are 2 oz of soup in 16 cans : False
In 1/8 of a can, there is 1 oz of soup : True
Explanation:
To start, we know we have 168 oz of soup and 21 cans that are all the same size. To find how much is each can, (We know that they will all have the same amount since it says equally sized cans.) we can simply divide the amount we have of soup in oz by the amount of cans we have.
168 / 21 = 8.
This means that all the cans will be filled with 8 oz of soup. Making the first statement true.
Since there are 8 oz in each can, we can do 8 cans * 8 oz to find how many oz are in 8 cans of soup.
8 * 8 = 64 oz.
There are 64 oz of soup in 8 cans. Making the second statement false.
Now again, since there are 8 oz in each can, we can do 16 cans * 8 oz to find how many oz are in 16 cans of soup.
16 * 8 = 128 oz.
There are 128 oz of soup in 16 cans. Making the third statement false.
For the last question, to find 1/8 of a can of soup, we can take 8 oz (8 oz in one can) and divide it by 8.
8/8 = 1
Meaning 1/8 of a can of soup is 1 oz of soup. Making the fourth statement true.
