<h2>Hello!</h2>
The answer is 1,6 alcohol servings.
<h2>Why?</h2>First, we need to know that 80-proof vodka contains 40% of alcohol, and a standard serving (at least in the U.S) is 1.5 oz (ounces).
<h2>Calculations</h2>First, we need to know how many ounces we have in 4 Jell-O shots.
So we have, 6 oz in 4 Jell-O shots
We know that no matter how many ounces of 80-proof vodka we have, there is always a 40% of alcohol. Knowing that we can calculate how much alcohol is in 4 Jell-O shots or 6 oz
There are 2,4 oz of alcohol in 4 Jell-O shots (6 oz)
To know how many alcohol servings are in 4 Jell-O servings (6 oz), we need to divide 2,4 oz by 1,5 oz (remember that a standard serving is 1,5 oz)
So
Finally, calculating, we know that we have 1,6 servings of alcohol in 4 Jell-O shots.
Have a nice day!
