A can contain 24 fluid ounce of fruit juice. how many pints of fruit juice does the can contain?
Serga [27]
<h2>Hello!</h2>

The answer is: 1,5 pints.

<h2>Why?</h2>

Firts, we must know that:

1 cup = 8 oz.

and:

2 cup = 1 pint

Knowing that, we can calculate how many pints of fruit juice does the can contain

If 1 cup = 8 oz. and 2 cup = 1 pint

So,

24 oz.*\frac{1 cup}{8oz.} =3 cup

We have that 24oz.= 3 cup

Then, calculating, we have:

3 cup*\frac{1 pint.}{2 cup.} = 1,5 pints.\\

So,  a can of 24 ounce of fruit juice is equal to 3 cups of fruit juice, and it's equal to 1,5 pints of fruit juice.

Have a nice day!
